"A good robovac is a life changer. Even a $350 basic S8. It is a great place to start. ... I promise you that you will not be disappointed by a basic S8. It will change your life even if it can't fit under every piece of furniture you own. ... My two S8s just finished vacuuming our entire house in about 46 minutes. ... While my floors were being cleaned, I sat comfortably on our patio in the cool shade with a slight breeze and composed my far too long response to you while sipping a diet soda and relaxing. ... I will have to spend about four minutes maintaining my two S8s. This will be my entire contribution to my home floor cleaning effort for today. Four minutes!"
"I got the Q5 Pro for $139. ... costs $450 less than what I paid for the S6 ... it is the best value option out there imo."
"Like 500$ these robots are currently the steal of the century ... You can get a mova p10 pro ultra (cannot remove its mops), equivalent to the l40/x40 for 500$ after a discount code"

"battery lasts me forever, I charge it once a week and I game every day."
"especially because of the battery life. ... The mouse I had right before this was the steelseries super light one, that was an every other day charge at minimum. Whereas this one is like once a week at most - and I work from home and game all night."
"Oh, and the battery lasts days even when exercising a lot (weeks without excercise)."

"its an incredible watch. ... I have never been happier. It is miles ahead of FR 255 in all aspects, workout detection, responsiveness, and functionality. It's amazing for $200. ... the quality, heart rate accuracy, and design are top notch and making quality products, most importantly - at a low cost. ... T-rex 3 is waaay better than $350-$1000 Garmin. I don't think its better than $1300 Fenix 8, but it can compete with it, there are reviews on youtube from credible youtubers comparing these 2. The fact that they are comparing and not finding too much of a gap between $1300 and $200 watches is more than enough to tell you how good T-rex 3 is."

"Improved swimming mode allows you to monitor your progress as you swim. ... The app syncs well with Health Connect (Google Fit) and actually syncs my swims as swims, not walking. ... The swim tracking seems accurate and the device is responsive immediately after getting out the pool."
"love it for counting laps"
"The coros was far more accurate in open water."

"App zepplife sync well with my iphone n strava."
"I would possibly argue that the app (Android) is an improvement over Zepp Life in many ways, it has dark mode, it transferred my Zepp data across and it has some additional features, like Sleep Animal, and AI insights that Zepp Life doesn't have."

"The app for accessing and retrieving the videos off the device remotely is a pile of crap!"
"The app. It's a complete pain in the ass to view any footage ... it won't update the firmware because the dashcam connects to my phone via wifi and if it's connected via wifi, there's not any actual Internet access from the cellular signal so it can never update 🤣 what a joke."
"Red tiger has the same issue. You can be connected to one WiFi connection at a time and since CarPlay connects Bluetooth and WiFi, if you connect to the camera, you disconnect from CarPlay. Then the Bluetooth kicks you back onto CarPlay again, booting you out of the camera. Basically you can only access the camera data by disabling Bluetooth and then disconnecting CarPlay to connect to the camera."

"I tried using my apple watch at an indoor 25 yard pool and it did extremely poorly. It was off by about 100 yards at the 1000 yard mark."
"Apple Watch will count a mid-lap stroke change (as you described) as two laps very reliably. ... For example: if you do 100IM in a 50m pool, it will appear as 200m IM in the Fitness app. ... So if you are really serious about loving mid-lap stroke changes I wouldn't use it."
"it’s absolute trash at tracking my laps even with the pool length set properly. ... It consistently tracks less than I do"

"The thing whoop is giving me is wildly inaccurate HR readings. ... Did a casual bike ride with my child yesterday afternoon and whoop gave me a 187 high HR. This was a really slow like 4 block bike ride. ... AW said 108hr peak. Ive biked hard, ran as hard as possible doing max HR tests with my H10 chest strap and never hit above high 160s. ... Im not sure whats going on but its been doing this type of odd HR readings all week."
"I had Whoop for three months and it started showing a very bad data. Like catastrophicly bad. ... Bought Polar chest strap to check my HRV, it was VERY different and was showing me my normal data, data that whoop originally showed to me as well until three months into use it stopped."
"HR reading on Whoop are known for being absolutely aweful. ... Better having an accurate reading every 5 minutes than multiple bad readings every seconds. ... Whoop has awesome software and data analysis, but makes it somehow unusable because of bad hr data in. ... If HR accuracy is not a problem for you, and only follow "very general trends", yeah Whoop is a cool product. But if you are at some minimal point serious about HR accuracy, for real sport / performance / improvment, you cannot relly on it. ... If a Polar device, Garmin, apple watch says it's at 80 with readings every minute or so, and whoop says 65 every seconds, your "constant readings" are not worth anything. Garbage in, garbage out. ... Even counting it manually with a timer and my finger on my neck would be more accurate. ... their linear HR sensors are poor quality, and not the ideal way of positioning them (VS circular patern)."

"Notifications are also useless—you’ll get an alert, but it just says something vague like “2 notifications from WhatsApp.” Even if you manage to read a message, it cuts off halfway."

"The Vivomove watches and the Vivosmart 4 and 5 also do not have built in GPS."
"There’s no GPS? So I’m supposed to have the band on my wrist and my phone along with me for all the workouts, to get the distance tracked?"
"The Vivomove watches and the Vivosmart 4 and 5 also do not have built in GPS."
I had 2 Fitbit charges (4 and 5) and both died at around 2 years. Currently using Xiaomi Band 9 and loving it so far.
r/japanlife • Recommendation for a fitness watch ->Wala yatang built in gps band 9. Currently using watch 2 lite, nagagamit ko kahit di dala yung phone and nag sync naman sa strava after.
r/PHRunners • Review for Xiaomi Smart Band 9 ->I'm using a Xiaomi Mi-band 9 to count laps. There's more, but it counts laps fine, is cheap and has a battery that lasts me a week.
r/Swimming • How do you record your swims? ->Xiaomi makes a decent smartwatch on the cheap. The smart band 9 is solid if you want sleep tracking/fitness stuff for less than $60.
r/fitness30plus • What's the best smartwatch for android currently? Has it really motivated you? ->I know that Greg Mairs uses Zoop. Personally, I use a Mi Band 9. It lasts for a couple of weeks and heart rate is quite accurate +/- 3bpm. OnePlus has a watch that tracks shots played and so forth
r/badminton • Fitness Tracker for Badminton players ->I got a xiaomi smart band 9 for $30 USD from Amazon a couple of weeks ago. If you're in the US, it uses metric units; idk if that'd be a deal breaker for you. I just wanted something cheap to track steps and tell the time, and it works great for that. There is a period tracker, but I decided not to use it. Didn't seem like the best idea, being a woman in the US.
r/walking • step / fitness tracker ->Wouldn't really recommend Pro 2 for that (either). It's just a nice looking watch with GPS. Xiaomi could be better.
r/CMFTech • Should I buy the CMF Watch Pro 2? ->Currently rocking a Xiaomi Mi Band 9 and it's pretty good. Battery life lasts about 2 weeks with my settings (pretty average). For ~$30 USD, can't really complain. My only real "complaint" is that it doesn't have NFC / Google Pay integration, because that would be neat. The Fitbit Charge 6 has it - but costs 6x as much. The app situation is a bit of a mess. DO NOT under any circumstances enable Health Connect syncing in the Mi Fitness app. It won't be immediate but after a week or so it will peg your phone's CPU to 100% and absolutely murder your battery life. The only solution is to uninstall/reinstall (for about another week). It's a long standing bug (you can find discussion of it going back years). So just don't do it. Also - older bands (7 and older) use the Zepp Life app instead. Which is also fine. The annoyance for me is I have the Xiaomi Body Composition Scale 2 which also only uses Zepp Life - and then the band uses Mi Fitness and there's no way to have them on the same app.
r/Frugal • Inexpensive smart watches for fitness ->I haven't tried walking in place yet, but I've jogged in place while wearing a Mi Band 9. (I'm not really recommending this watch... I'm sure there are better ones on the market. I only settled for this one because I'm a cheapskate lol.. But it serves its purpose, for the most part. ) Whenever I jog in place while on my phone, I hold the phone and scroll using the hand/arm that isn't wearing the watch (i.e. right hand). I continue swinging the arm that is wearing the watch (i.e. left arm). I've also seen videos and read about people wearing their watches on their ankles instead, whenever their watches are undercounting steps due to lack of arm movement... like if they're on a walking pad while working at a standing desk... I might try walking in place and wearing my watch on my ankle just to see how it goes.
r/walking • fitness watch that tracks walking on the spot? ->Just so you know, I did an experiment wearing my Mi Band 9. I walked in place for five minutes in each scenario. Here are the results: .a) wearing the watch on my ankle - I'm not sure how accurate the heart rate is, since these watches are meant to be worn on the wrist. But it picked up my step count just fine. .b) wearing the watch on my left wrist, making sure to keep my left arm swinging. ( I was holding my phone in my right hand and scrolling , so my right arm wasn't swinging.) It also picked up my step count just fine. .c) wearing the watch on my left wrist but holding on to my phone with both hands (no arm swinging). The watch did not pick up my step count at all, and it said that the distance was too short to record. Conclusion: If you're going to use a fitness tracker/watch to track your step count while walking in place, you need to be swinging at least the arm that is wearing it. If you won't be swinging your arms, then wear the watch on your ankle. I'm not going to recommend this brand/watch. There are probably better ones out there. I was just curious and wanted to know for myself if it would detect my steps while walking in place. PS. I have a pedometer too, I might also test that while walking in place. But based on my previous experience with it, it doesn't detect my footsteps when my footsteps are too light. Or maybe I just got a bad one. https://preview.redd.it/zjy8e1cva4df1.jpeg?width=1080&format=pjpg&auto=webp&s=f7957f7875e5d14d16013b475e0e7dfb83d0a2d5
r/walking • fitness watch that tracks walking on the spot? ->overheating shut down on the 9, doesnt take much just needs to be in the sun on your wrist in 25 celsius . take your charge cable with you when you travel else your watch might be off until you get back home which could be days,.
