Tbh save up for those chinese mice if you trust them enough. I have bought 5 50$+ mouses from chinese manufacturer with PAW 3950, they are ALL WORTH IT. Right now im using ATK F1 Ultimate, but im changing to Attack Shark R6 just because ☺ Making this for you if you're thinking of upgrading to a PAW 3950 mouse
ATK F1 Ultimate, i used to main a deathadder chroma and later a viper mini which both had great shapes and fit my hand well, but the heavier the mouse, the harder it is to aim since i have some serious weakness and strain issues ( probably from overplaying with bad posture for years ) The ATK F1 partially solved this because of the extreme low weight ( 35-40 grams ) and very light clicks.
Have the atk f1 ultimate v1, everything is great except battery life and the v2 solves that problem.
The main differences are the shape and sensor position. The A9 mini is a smaller G pro X superlight, the F1 is similar to the viper mini. I haven't tried the A9 mini (yet), I do own the F1 and I love the shape (the button height being low feels nice too). If you've ever tried the viper mini, or the viper v3 (and felt it was too big) and you liked the shape- the F1 is a good choice, but beware that the sensitivity (specifically the X axis, side to side movements) might feel a little sluggish due to the sensor being rear- biased. If you've tried the G Pro Superlight and even if you didn't- the A9 Mini is a very safe shape, and the sensor being a bit more forward is better, since it's closer to where it is on your current mouse.
If you want the Viper v3, the size would very probably be an issue. The F1 feels like a smaller and somewhat better version of the viper shape in my opinion, with the upside of the low button height, and the downside (imo) of the low sensor position. I could full heartedly recommend the F1 if I didn't dislike the sensor position as much, but the sluggish feeling I mentioned doesn't seem like it would bother you- go for it, or wait for the v3 to release soon, it should have a higher sensor position.
Atk f1 v2 with new mcu - viper mini shape clone - it would be so good for your handsize or Atk u2 v2 mini for more locked in feeling claw grip. For more budget options take a look on Rapoo vt1 original shape but similar to lamzu maya Rapoo vt0 ninjutso sora clone. U can buy rapoo with free shipping from 35$ with code for 20% discount. All of these have new nordic mcu with superior battery life. I just recommend mices with new mcu cause its just better.
Ultimate for big battery life.
I have the F1 V2 Ultimate in pearl blue It is perfect, no issues but I would go for the FE optical switch to Omron optical and the battery from 300mah to 600mah to get double the battery life after that it is a mouse with no flaws in my heart
I own the F1 V2 Ultimate the reading eye is not placed too far back, but placed in the middle compared to the HyperLight with the same style but the reading eye is placed high up in the front It's up to you which option you prefer, but I like the internal parameters of the F1 V2 better
