Surface

There are two color variations available for this mouse; there is a black and a white version, and they both look very sleek if you ask me.


Pretty much the whole mouse shares the same surface treatment, which is a matte, slightly roughened plastic coating. There is no rubberization on any of the surface areas, which can be considered both bad and good news. The mouse may be slippery for some people; however, there is no chance for anything to peel off. There are also a lot of DIY methods of making the surface more grippy since several pre-made grip/gun tapes are available, and you can create your own too; however, most people will probably not have any issues with the coating anyways. I have quite sweaty hands and never had issues with the G102 I used for months, and the G305 has the exact same coating as the G102.

Build Quality

Fortunately, I couldn't find anything to nitpick on the G305's build quality as everything seems to be solid and perfectly in place, including the mouse feet. There are no rattling, squeaking, or creaking sounds even when gripped very hard. The G305 is put together very nicely.

Weight

The G305 weighs about 99 grams with an AA battery—at least with the battery that comes with the mouse by default. There are a number of options to make it lighter, and my favorite choice is using an AAA lithium battery with an adapter. This gets the total weight down to about 87 grams, which is pretty impressive for a wireless mouse this size. However, it could still be lighter as we have seen with the PRO wireless (even though the two mice aren't in the same price league at all). An easier method is to simply use an AA lithium battery, which puts the weight at around 90 grams.
