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).
