I previously bought a cheap, “ergonomic” mouse but the sensitivity on it was terrible and didn’t pick up movement well at all. This mouse was a great investment and the sensitivity is perfect. Only the is that the shape sometimes hurts the bottom of my palm after long use but if you get a good mouse pad this should be no issue. I say get itShowed up on time and my son loves itI overall really enjoy the mouse. Great response time with no input delay for it being wireless. However, this mouse doesn’t have a good battery life. I constantly have to charge it after just a little bit of use. I’ll charge it to full and then after an hour or two of playing, it’s needing to be recharged.I want to like this mouse a lot based on performance and ergonomics, but both are pushed to the side with the trash battery life.My son loves this gaming mouse. Just received a week ago so k can’t say much for durability but everything else works greatThis mouse has a good design and structure, i found no problems with the overall shape either, BUT!! the mouse would lose tracking VERY easily when playing games. im not sure if it was my product in specific but this mouse is not for fps gamers that are looking to play competitively!!!!!!Overall I loved the mouse, the wireless connection parallels a wired mouse. I picked this mouse up hearing great reviews and because it looks pretty damn snazzy. Ive had it since April 14th, 2021 and already, the roller has started to squeek on me. Yes, this is not a HUGE problem, but it is incredibly annoying when you spend spend over 100$ on a mouse that is supposed to be higher end. Finally, the battery life is terrible, I have to charge the mouse every 28hrs, give or take a few hrs. I'm sad, I like the product a lot, and would love to suggest it to others but it seems to fall extremely short of it's market value and I can't help but wonder if I was sent a refurbished mouse. I used a Razer Deathadder wired for over 10yrs and never once had any problems with squeeking rollers. Literally 2 months in and it's come to this.. sigh...Loved the mouse, 400dpi feels great wireless, annoyed because I ordered the white one and received the matte black one, really not a huge deal, but silly on Amazon's part as the white was more available and cheaper(on top of fitting ny needs better as well) but didn't have time or wanna spend the money to ship it back and wait longer. Mouse is brilliant regardless of color, my issue is with the retailer ?I've got it, I got rid of a random Roccat one for it after everyone and their Mum telling me how good this was, but I didnt find it any better..the keybinds on the mouse are a bit off too, they have this thing where if you click a button on your keyboard and the bind, it will disconnect the bind for a quick second to register the keyboard- you don't get that on other mouses.... (example, crouching and checking map will make you stand up)just look into that if that'll affect your decision, but its just a mouse.. nothing great about it.Another additions of glorious mouse into gaming mouse market. Mouse feels cheaply made. Do not understand obsession with holes in a mouse when other manufacturers are showed that is possible to make light mouse without drilling bunch holes in it.Sensor feels really off at least in the mouse I had. Right click was rather wonky.Not a good experience. Lasted < 4 months before it died completely. The return process I had to pay for and then the vendor refused to investigate because it was too dirty inside? No explanation of why the item was dead - did they actually test it and find the root cause? No! Premium product at premium price but doesn't have anything to prevent ingress of dirt & hence apparently breaks after a few months? No warning of its vulnerability to dirt ingress. Liquid damage was also raised as a possibility but no evidence presented. No empathy or offer of good will gesture from vendor. Unhelpful and disowning responses.Conclusion: Very poor vendor interaction, in fact the worst I've experienced on Amazon.Update: Amazon enabled me to submit an A-Z claim which I won. Amazon refunded full price. Thank you Amazon!The cps (clicks per seconds) are really good with this mouse. It lights up in many different combinations & patterns, it can be set to however you like it & whichever colour/s. Worth the money & can either be plugged in or wireless.Upgraded after my wired model o broke, and it is a great mouse. No delay or issues at any point since I bought it.
