Pros: Driverless install. 3 polling rates. 3 dpi settings. Positive dividers in scroll wheel motion. Scroll wheel click (middle mouse click) is just a little bit heavy, but still very good. Forward/back buttons well placed. Sheathed cable is firm but not too rigid and is of generous length. The optical sensor is an Avago 3050 which is found in much more expensive mice. It is a very accurate and stable sensor. I like the size. It's mid-sized much like a steel series ikari or sensei, but slightly taller.

Cons: DPI settings are fixed and your choices are 500, 1000, and 1750 dpi. You can't set a custom dpi, so it's next to impossible to exactly match your previous mouse unless you had your dpi set to one of those exact settings. The red logo and red LED under the scroll wheel can not be turned off. They aren't extraordinarily bright, so that's minor, but I'd prefer to be able to turn them off. Because it's an optical sensor, the lift off distance is pretty high (maybe 5 or 6mm) and some folks might have a tough time getting used to that. I don't mind it too much because I tend to lift higher than necessary, but it can take some getting used to if you've come from running a laser instead of an optical sensor.

OK. None of that is major, but the reason this is a 4 egg review and not a 5 egg review is that this mouse has slippery sides. The name of this mouse is "Grip 300" and its name would make you think it's easy to get a nice grip on it. It's not. While the sides are matte finish, they sure have no texture and not much 'grippiness'. For my mousing style, I am absolutely going to have to make some modifications to create some texture. And finally, the dpi change switch is on the bottom of the mouse... so no on the fly dpi changes. So, you snipers are going to stress about not being able to have a high dpi setting for close quarters combat while you fight your way to your snipers nest and an easy method of shifting your dpi down for precise sniping.

Other Thoughts: As the title of this review indicates, I'm pretty convinced this is probably the best optical gaming mouse you're going to find at or near this price. There are plenty of superior mice on the market, but you're not going to find anything vastly superior to this one until you are spending at least twice or three times as much money. This one is a really good value.

Pros: I like the price and capacity, and I've always had good luck with G.Skill memory. I wanted a 2X8 16Gb kit and there are only a couple currently available at or near this price tag. The other one currently available for just a few bucks less than this one is from a company I'm unfamiliar with and that kit lacks heat spreaders. While I'm not really sure how necessary the heat spreaders are for my situation, I like the look of these and I trust this manufacturer.

Cons: None. No cons what so ever.

Other Thoughts: I bought these for an MSI B150 board. I have no intention of overclocking them and they run just fine stock on an MSI B-150M Pro-VD with a non-K i5 6600. Plug them in and they work. That's what I wanted. That's what I got.
