Razer Viper Ultimate Gaming Mouse

Context for the review:I have used this mouse for a long period of time (At-least for me), this being close to a year, I bought it with no charging Dock.I daily use this with my two computers, a gaming laptop and a gaming PC.I have moderately large hands.My average mouse breaks within 5 months. That should say how much I use my mouse, not counting how rough I am on my mice, such as when sliding & lifting them across my mouse-pad or the occasional accidental drop. This lead me to typically only buy Razer mice, because all of the other main brand mice usually break around the 5 month mark for me.This is not to mention my original Razer Deathadder V1 mouse lasted 7 years of VERY harsh daily use, and only failed because its scroll-wheel broke. (Abbreviating Deathadder to DA from now on)That's not to say I haven't had issues with Razer products, my first DA V2 lasted 1 week until both the left click and the scroll wheel started failing leading me to then use the other brand name mice; G502 Hero lasted 5 months, Corsair M55 lasted 2 weeks,and the HyperX Pulsefire Haste lasted 3 months.My next Razer product was a DA V2 pro and that one lasted 2 years, Which led me to buy this one after that one started not sensing right clicks.Issues:I had zero issues with it for 8 months, then, entirely out of random, started having weird issues with connectivity. This started out with very minuscule connectivity issues, such as it waiting 30 seconds for my PC and Razer's software to start working properly to use the mouse when it gets turned on after being off for a while.This was annoying, but I didn't care too much about that since I could still do whatever I needed to do.But fast forward ~4 months and the issues have compounded a little bit and I get my connection cut off when playing games for a solid 4 seconds at a time, and at this point this is getting REALLY annoying to endure (This happens plugged in too).At this point I am also having issues with the mouse having a slowed reception & it being able to hold a charge for more than half a day. I used to be able to use it at it's highest pulling rate and low brightness of the LED for 5 days without charging.Positives:Very durable plastic, I have very little wear on the mouse besides a bit of wear on the left click plastic making it shiny instead of matte black.Very comfortable if you claw grip your mouse (Not comfortable if you palm the entire mouse).Very light and easy to move on a mouse-pad.Fairly priced, ~$60 is quite decent for this mouse.Lasted 10 Months until having some bigger issues (Most mice completely break around the 5th month for me).Scroll wheel is perfect, zero squeaking (like a Corsair M55) or aggressive rumble feeling (like a Logitech G502) and has a good rubberized texture to it (HyperX Pulsefire haste didn't have any great texturing).Great for putting into a schoolbag for college or for storing in a laptop case.Buttons and sensor are great and feel immaculate.Cons:Either the USB dongle, or the mouse itself is having issues cutting out and not working at random after close to a year of use. The same with sensitivity, it has definitely gone down for the sensor.Battery is now starting to have issues holding a charge.This is where I am currently at with this mouse, It has worked very well for what it is, but I may soon have to upgrade, due to the issues I am having.You will probably have a longer service life on your mouse though, especially if you are not rough on your electronics.I would 100% recommend this if you need it for a laptop and need it to be wireless, or have smaller hands that are not as fitting for a Razer Deathadder.
