If there's a deal on this, get it. It works good and will last. The customization is great. the "9 buttons" include the scroll wheel left and right clicks, which I found out I don't like. I never use the sleep function on this mouse/ never seen it in action. It works better than any other mouse you'll find in a Wal-Mart but that's honestly the best I can say about it.

I've had this mouse for a while now and it's still incredible. It's very responsive and works wirelessly and with a micro USB cable.

Mouse has served me basically all day every day. This mouse is used practically 9-5 every work day on top of my gaming time when not working. Zero issues from it up until about what looks like a year after purchase, and the scroll wheel no decides to either scroll more than intended, or roll the opposite direction. Tried dissembling and cleaning out the wheel/carriage and sensor area, but that only was a temporary fix.

Not sure about the current state of Razer, but them being a major player in the peripheral market, I wish the product lasted longer. Going to attemp an RMA and see if they can replace it. Their site says it has a 2 year warranty.

Bought this mouse because I wanted to cut some cords and I do spend a good amount of time gamingand Razer is a well known brand in the gaming community. The mouse is not one of those over complicated mice that have about 13 buttons and a sink stuck to the side of it which was perfect for me, what it does have is 2 buttons under the thumb which are SUPER convenient and SUPER easy to press/reach (suits my needs in World of Warcraft perfectly). It has a little but of Chorma light on the mouse wheel and of course naturally the Razer symbol lights up beautifully. Software was easy as 1,2....done, as soon as you plug the mouse in the installer wizard takes off and before you know it you are done. I love I can customize the lights in a dozen or more ways using the software and I can match the lights on the mouse to the lights on my Razer Kraken Kitty edition headset ( I have a pretty fly set up). The material of the mouse is NOT what I had expected it to be, photos are deceiving. Initially I was disappointed I had thought it was made out of that soft touch plastic but it wasn't but now I kinda like it just the way it is and think it's a great choice (the soft touch plastic would get greasy/oily/dirty in no time). This mouse is EXTREMELY light weight for a wireless mouse which was a great surprise (I think its only 4 oz) while my wired mouse weighs a ton compared to it. The plastic the mouse is made of can seem like it's cheap but I assure you - touch is deceiving, it's a tough - durable mouse that's overcome with flying colors being dropped, sliding off my table and *drum roll please* a TODDLER harassing it non stop (toddlers are like fish - show them something shiny or color changing and they are hooked). The overall shape of the mouse is underwhelming but that's not a bad thing, it's actually kind of perfect truth be told, it fits in my hand so well it's like I had been using this mouse for the last 10 years and had worked it in already...that's worth it's weight in gold in my books.Now time for the bad...

The bad...

While the mouse is meant to be a wireless mouse there are times it does need to be plugged in (to charge and it does work just as well plugged in). The Razer store page for the Mamba clains it lasts 5 hours however after 1.5 days of use or a full 24 hours the mouse starts to blink red which signifies it needs to be charged. That's rather fast, much faster than I was expecting. I turn the mouse OFF when it's not in use so it's not irresponsible ownership draining the battery. I feel like every time I'm turning around the mouse is screaming at me it needs to be plugged in. I did not enjoy trying to figure out how to charge the mouse - that made me chase rabbit trails. I tried the book, I did't find what I needed in the book, I tried Google but Google referenced some sort of charging dock which is no longer made or sold, I tried plugging it in and charging it with my apple block I tried plugging it into the laptop and none of that seemed to work (even over night plugged in) turns out it needed to be plugged INTO my laptop and the switch underneath needed to be in the OFF position, such a simple thing you'd think I would have assumed that. Once I clued in it charged like a charm.

Last thoughts...

I love the mouse despite the poor battery life and the fact I still feel connected to wires. It looks good, feels good and works amazing!! Hands down best mouse I've ever bought for gaming and I've been gaming a VERY long time (23 years to be exact). I will definitely buy another when this one dies (provided they are still made and sold by that time). To tell you how good this mouse feels I told my husband if I was rich I would buy EVERY single person in my WOW guild (retail AND classic) one of these mice (yes it's that good imho).

This was previously Razers top tier mouse. Featuring top of the line everything from sensor to lighting, to being wireless, to having its own stand. The Mamba is what started the trends and was the pinnacle that other mice tried to replicate.

However, with this, the second generation, Razer made a dire mistake. They released the Mamba Tournament Edition, trying to cater to hard core gamers, but unfortunately, they chose a laser instead of an optical sensor and it had some performance issues compared to Razers other mice which all used optical sensors and because of this, the mouse got a bad reputation.

Razer later released a newer version, updated with THE BEST optical sensor made at the time (still great even today), better than all others, with Omron switches (best at the time and still great today) and it solved all the problems, but by then, the name "Mamba" was synonymous with shitty lasers, and so no one went after it, and there were barely any reviews.

But as someone who had a Deathadder that finally bit the dust and wanted an upgrade, after testing out every mouse there was, my choice came down to either the Razer Viper or this Mamba, and the Mamba just felt perfect for my large hands. Thumb buttons were perfect, shape was perfect, and even the side grips were placed so much better than my Death Adder.

Additionally, it's one of the very few Razer mice that offers mouse wheel tilt, which gives it 2 additional buttons to hotkey, which was a game changer in terms of competitive gaming.

I still use and adore it to this day and I've tried a lot of the latest models and I still like this mouse. If you have large hands, are right handed, and want a somewhat basic mouse with the best sensor (I think it might still be Razers best) and two more programmable buttons than a generic basic mouse, then give it a try. It's under 100g which, although not as light as a Glorious Model O, it's still lighter than most none-perforated mice (mice with holes all over it to save material weight).

This is still the best mouse in Razers lineup, in my opinion. At the very least, the most underrated.
