Summary: When I bought the mouse, I was overly excited to use it. It replaced my Deathadder which stopped working. My biggest con with this mouse is that after 3 months of continuous use, the rubbers on the side has rubbed off at a certain spot revealing the plastic material. I decided to go back to the Deathadder for my personal home use and have brought this into work.
Pros: The rubber feels amazing in your hand
Cons: Rubber on the sides have rubbed off in two different areas
Summary: The mouse is very good, but even after 2 month, I can't use it to it's full potential has Steelseries have no drivers for Windows 8.1 (even if it has been release today). When you install the drivers for Windows 8 on Windows 8.1, it litteraly "broke" Windows files (C:\Windows\System32\Drivers\steelbus64.sys block Windows 8.1 from booting). It's a major issue and Steelseries know this from june 1st and still no new release of the software yet.
Pros: Mouse react quickly, nice design
Cons: I often missclick the right side button (it's an ambidextrous mouse). Steelseries got major issues with them software.
Summary: Worked great, but didn't last. I have heavy hands and play a lot of RTS games, but all of my other mice have survived the same abuse for many years. The Sensei RAW barely lasted the summer. I might buy another SteelSeries product...if they could convince me I wouldn't need to replace it in a few months. I would rate this at 2 stars but I don't remember my order ID.
Pros: Good mouse, great response, engine is easy to use
Cons: Engine uses 70k memory, climbs higher after long use, right click died after 4 months of moderate to heavy use
Summary: Build and parts feel great, there is allot of quality in the mouse and software. Really Honestly wish they made this mouse in a right hand style! It is a great mouse but if I can't get use to gripping it the way Steelseries wants I will have to replace it with a mouse more for my grip style. I use Merc Steelseries keyboard which I highly recommend to anyone and wanted to use a Steelseries mouse with it. Cheers hope this helps anyone making a choice.
Pros: Extremely well built mouse, feels solid in all areas. Nice click sound, mouse wheel firm: no sloppiness. Tracks mouse pointer accurately, best i have ever seen. Software package is all I need to get the mouse working.
Cons: Shape, my hand gets sore. I think this mouse is meant to be used with a claw grip style. If you use this mouse as a regular right handed mouse, this could present problems. I don't need buttons on right side. The mouse feels like it's a left hand mouse which is odd.
Summary: be warned if you buy one of these that the mouse wheel is incredibly loud when being rolled upwards. The mouse itself performs well in gaming and in normal use.Its just the damn noise,even my friends could hear it on our teamspeak. All the mice i have had in the past even my back up Tesco mouse is quieter than this,so this is something that needs to be addressed by the company.
Summary: If you have dry palms, this mouse is going to be slippery. Horrible grip. A $15 Dynex mouse (the old model that had rubber grips, not the current one) provides a better grip than this. So if you have a claw or mixed grip and hoped that this mice would provide you with a nice grip to pick-up your mouse, nope. Keep searching. I bought mine yesterday and I'm going to return it.
