@lexluthermiester I think you use this brand? Not sure they worth it mate. Amazon has so many good sales these days you really don't have to go super budget these days.
My experience has been very positive with Redragon. The keyboards and mice have been of good quality and the software solid & unintrusive.
This particular model is not something I would go for as it's wireless and I prefer wired. Also not a fan of the shape and size but those are personal preferences.
The latency of 13.5ms is only going to be a problem in ultra competitive gaming situations. 14 one thousands of a second is not something a user would otherwise notice in normal daily activities or even non-competitive gaming.
The battery is acceptable, but me being the tinkering hackster that I am, I would replace that battery with a 2000mah or 2500mah version very quickly.
Firmware likely needs some tweaks and an update.
Otherwise, I'd say this is a good offering from them.
EDIT:
On the subject of latency, I would submit that 14ms is not a bad response time. When we consider that most wireless controllers are deemed good at 70ms to 80ms and excellent around 60ms and wired controllers perfect at 40ms, for a mouse to have 14ms, is nothing to complain about, even if it's slower than the competition.
