In terms of size, the ARCTIC M551 is about the same as the Logitech G7 Wireless. This makes the ARCTIC mouse a good size for a gaming mouse.

There is one thing I noticed about it: although its length is about the same as the Logitech G7, the back of the ARCTIC M551 is narrower. Because of its narrow back, the ARCTIC mouse does not reach the palm uniformly and, as such, it does not fit snugly in the palm compared to the Logitech G7.

In terms of height, the ARCTIC M551 is slightly shorter. It is less inclined compared to the Logitech G7 too. The ARCTIC M551 is comfortable to grip for the right hand. I still the Logitech G7’s grip over ARCTIC’s mouse, however.
