Xiaomi - Smart Band 10

Xiaomi smartband 10. Was a 100% deal for me. I saved $1000+ not buying Garmin

Mine is Xiaomi SmartBand 10. Very cheap, and helpful in pool. But it doesnt track the openwater

Xiaomi Band 10 , unbeatable price , most accurate counts and Spo2 (near to apple watch) and battery is great too. It won't have phone features like calling/mails and stuff but as a fitness device it's the best.

If you really just want time and distance for lap swimming, I've used the previous model of this $62 watch, and it worked fine: https://a.co/d/7ChjCyh I eventually upgraded to a Garmin Instinct 2 because I wanted GPS for other activities and the ability to export more of the data. I'm very happy with my upgrade for the other features, but I don't think it's really any better for time/distance measurement.

I bought MI Band 10

My friend was in Dubai, so I asked him to pick it up for me. It cost me 3.5k.

Xiaomi Mi Band has been the gold standard forever now. Also buy it on Ali Express, not Amazon or your local Xiaomi store, it's much cheaper. The Mi Band 10 is £40 - but the 9 is £35, so depending on how strict he is about the budget. I've been using the 9 for about a year so far and it's pretty good. Battery life is about 2 weeks (but will depend on how you set it up). At least when compared to my phone's (Google Fit) step tracking it's pretty accurate, and when compared to the heart rate reader built into my gym's cardio equipment that's reasonably accurate as well. Kinda wish it had Google Wallet support for easier NFC payments but it is what it is - otherwise can't complain.

I bought it some days ago and just tried it today. It recorded less than half of the strokes and only about 25% of the laps (19 out of 70) :-(

Update. I have looked into how it works and tried some different approaches: It counts pool lengths by combining the acceleration when you push back from the edge and the wrist movement to detect a stroke. The first time, I was often switching between freestyle and backstroke and it missed 80% of my laps. If you stick to one type of stroke (freestyle or backstroke), then it's actually quite precise. But every time you change the type of stroke in between pool lengths, it systematically gets confused and doesn't count that length. The solution I found if I want to switch strokes during a workout is to change in the middle of the pool. If I finish a length in freestyle and want to switch to backstroke, I will start the next length in freestyle and change to backstroke after 2 or 3 movements. The the watch has the time to adjust and it counts the number of pool lengths accurately

It’s a smart band but might wanna check it outXiaomi band 10 is pretty great value

The best one you can get for that proce is the Xiaomi mi band 10. New. Better battery that most others.

For swimming I recommend mi band 10, is very accurate

I use a xiaomi mi band 10, it cost me 40v euros, and it's pretty great :) I've always been vary of wearing expensive electronics in water so I've won't mind losing the xiaomi band when the seals or gaskets fail after 3 years or smth. Plus this band has had no buttons or mic or speakers so it's actually water right.  Anyways, the lap tracking is nice as well as stroke type detection. It uses the acceleration sensor so it will count a finished lengthv when you rest. Plus you can measure HR underwater that's nice.
