Long story short, I'm a self employed futures trader and I at the age of 32, started PC gaming as of this February. Honestly, 99% of the time all I play is CS GO but after learning how "regular" blue-tooth or optical mice were NOT sufficient in gaming I decided to go on a search.... With price not a concern, I literally spent around $470 on mice trying to find something that just felt "PERFECT"... From Zow ie ECA-1, Logit ech G-pro wireless, Logitech G502 Pro, Cor sair M65 pro, and the list goes on... NOTHING felt right in ALL THE DEPARTMENTS. Sadly, I was brainwashed by online reviews or blogs talking trash on "RA ZER" products as they spend all their money on marketing and are cheap lower quality gaming items. I do have large hands (not big enough to palm a basketball) but every mouse felt too small which made my fingers and wrist cramp OR the mice were just big, awkward, overloaded with buttons, etc. I am naturally a palm grip style gamer but I do like a lightweight mouse because with CSGO long entire arm movements are key to becoming a great player... After trying all these different mice I decide to settle on a Logi tech G305 Hero wireless mouse which I use a lithium ion battery along with a AA to AAA converter housing and then I drilled holes in the mouse to lighten it even more (and for a rainy day project)... It has been my go to mouse but its SO SMALL... I've gotten really good at using it but I saw randomly on Best Buy's website the Razer Deat hAdder Elite dropped in price to ~$45. I LOVE my wireless Logitech HERO sensors but this mouse has been around for a decade or so... I figured for $45 plus a $5 three year replacement plan I had to try out this mouse and RAZE R products... WOW!!!!! This mouse instantly fits the contours of your hand, perfect size even for LARGE hands yet still very lightweight feeling! It does not have 16 programmable buttons but a true FPS gamer does not need any extra BS, I would be happy if it didn't light up but it's whatever... Anyways, after a solid 7 hours of gaming non stop my movements and shots are NUTTY! Yeah its wired but it's SO MECHANICAL feeling and the buttons are "crisp"! I was concerned about the reviews and people ranting about how the Razer Synapse software dramatically slows down your machine and runs tons of unnecessary processes in the background... When you install the software they give you OR try to get you to install around 6 different programs when you can disable them and install the basic software, EASY! Then, disable Razer from auto-starting when you boot and even exit the synapse program totally and the mouse works flawlessly! I NEVER WRITE REVIEWS ON ANYTHING BUT DANG THIS MOUSE IS WORTH $200-300 IMO it's actually priceless the way it fits the hand and performs! Do yourself a favor a snag at this price!
