Summary: Some Background - I own multiple Razer products, starting first with a Deathadder which I loved dearly. After many years of use the left button stopped "clicking" it was just soft and squishy with no action. I looked around and thought about getting a new Deathadder, however the Mamba appeared to be a wireless version of the DeathAdder, which sounded awesome so I ordered it. I purchased this mouse in 2011 and have never been "Happy" with it.
Summary: I use a mouse in my business (Graphic Design) heavily on a daily basis. I've owned a bunch of Logitechs but decided (after my Performance MX started acting loopy) to try a gaming mouse in the hopes that it would hold up to my requirement of accuracy and solid build quality. But this was a major disappointment. The software installation was obtuse and the website cryptic.
Summary: I purchased this mouse April of 2013. The mouse worked well but a few months down the road it started performing very oddly. I thought it might be just me or driver issues but now it is conclusive. When I am gaming the mouse will get stuck only moving horizontally or vertically and I have to unplug to reset it.
Summary: I bought this mouse despite all the reviews mentioning a distinct lack of reliability. I quickly learned that Razer deserves its reputation. The mouse ceased to function wirelessly within a couple of weeks. Thankfully, I was within my return window. I stupidly returned the mouse for another Razer model, the new Naga mouse. Luckily, it hasn't died yet, but the sensor has been going in and out. Additionally, Razer's software is absolutely terrible.
Summary: So I have been a long time Razor customer and have purchased their mice for years. I recently purchased another mouse and found out it was defective. I returned it, purchased this one instead, the mouse seemed great, at least until today when the battery stopped charging. I am not sure if it is the battery, the charger or the mouse but I now have a $110 corded mouse that won't work.
Summary: I've had 3 of these. 2 from Amazon, and 1 from eBay. Each of them have had problems with wireless mode on MULTIPLE computers, and the most recent one to die was even failing momentarily during wired mode. They each had poor battery life, one of the mice had a right mouse button that didn't click properly. It wouldn't make a sound so sometimes I wouldn't know I had it down. It also became oversensitive and for a gaming mouse that's not good.
Summary: I went through 3 razer mambas in the span of 4 months. The first one I was pleased with until the buttons stopped functioning. The RMA they replaced it with came with cracked plastic where the battery level was shown. The second RMA came with a sliced up and broken scroll wheel. Junk after junk after junk. However, I had a first edition deathadder for about 5 or 6 years. It's quitting on me now, disconnecting and stuff. It's dead. So I'm here to look for new mice.
Summary: I decided to get this mouse thinking it would be an upgrade from my old broken 2010 Mama (which was a nightmare to get working properly). After I was sent my first mouse I immediately had the issue of the mouse not allowing the computer to stay in sleep mode. This still has not been fixed and all Razer could do was tell me to reinstall their drivers. There was also a bubble in the rubber thumb pad that was extremely irritating and uncomfortable.
