When I first saw the R.A.T 7 I thought “what an ugly mouse” – now I look at it on my desk and think “this is a thing of beauty”.

Let's go through it's features.

DPI: Ok Cyborg make a bit if a deal about the 5600 DPI – I personally find this is too sensitive – and have it set to 3200. However I do like the ability to change the DPI on the fly and there is a button by the scroll wheel that you rock back or forth to either increase or decrease the sensitivity from 5600 down to 800 when you want to be more precise – for instance using a free select tool in an image editing program like GIMP.

Profiles: I've used this for a couple of games in setting keyboard commands to the buttons and side scroll wheel – you do need to remember to activate the profile before starting your game. It's a useful feature but not one I use a lot.

Customization: Now we're talking – this mouse comes with a very nice tin case which holds 2 more palm rests a weight cartridge and 2 pinkie rests. One of the palm and one of the pinkie rests are rubberized – I tried this and while it gives good grip I didn't feel so comfortable with it as the smooth ones – still it's nice to have the option.

Using the built in screw driver you can move around almost everything to suit the size and most comfortable position of your hand. I swung the thumb rest out and forward a bit which feels more natural for me.

The real kicker for me though was attaching a pinkie rest which elevates my finger above the mouse pad – no more dragging a finger across the desk!

A friend just purchased the R.A.T 5 and I see it is nowhere as adjustable as the 7 nor does the 5 have a pinkie rest. I'd recommend if you have the extra dollars to invest in the 7 rather than the 5 if you want a more comfortable mouse – if you just want the profiles and 3600 DPI the 5 offers then the 7 might be too much mouse for you.

I spend most of my entertainment time at a PC and find this a very comfortable mouse – it has a lower profile than most so when I go back to my work mouse I find myself grumbling about how uncomfortable that is in comparison to my R.A.T

I bought this mouse as I was tired of my wireless mouse needing recharging and didn't mind returning to a cord – the R.A.T has a good quality braided cord which looks pretty tough.

Overall I am very pleased I spent the extra dollars for this mouse – it is very comfortable, feels well engineered in my hand, looks unique and performs very well.

I'd recommend this as a solid choice for both gaming and heavy PC users.

This mouse is amazing, I upgraded from my Logitech mx518 mouse, and the two just don't compare.

Some people say that the customizing is just a niche, and no one will use it. Not true, I've seen a few people using this mouse and each one is set up different. It is so comfortable and easy to use. Some of the buttons do feel a little… Off, but that might just be mine.

The biggest problem is the fact that it is too sensitive, when you are listening to music while playing, or a grenade goes off next to you, in game of course, the bass makes the mouse move slightly, and at 5600 dpi a slight movement = a big jump on screen.

Also, I have read that the mouse needs the right mouse pad/surface to play on. Not necessarily an expensive one, just the right one, apparantly the sensor has trouble tracking on some surfaces, but this is a sensor problem, all mouse that have this sensor in them have the same problem.

Overall I would really reccommend this mouse to anyone that is serious about using their computers, just do some research on it, there is alot of reviews out there and they will tell you what to expect.

I owned one of these mice for two years, it worked perfectly and I loved it! When both the left and right buttons were constantly double clicking I decided to play it safe and replace it with the same mouse. However, I have found that this new one is of a lower quality than the first. I am not sure if this is just my one, however, I have found that the palm and pinky rests wobble in place, and it simply feels as though it is made of cheaper, and worse, materials. Given the chance I would not buy this mouse a third time!
