Bests & Worsts Reviews from Amazon

INTRO: I've owned this mouse for over three years and have never been gentle with it. It's gone overseas stuffed in a backpack, been used as a makeshift pillow (on those late night gaming sessions where the body quits before the will...), been stepped on, dropped, left in the sun, left in the cold, and has even had an accidental steam spa session in a hotel bathroom. Now it spends its days shoved in a backpack to and from my university. Like I said, it's never been treated gently. And yet, it's going strong. It's as responsive as the day I got it (there is zero input lag and anybody who tells you differently needs to review the he response rate of the human nervous system, which is slower than this mouse), the lettering hasn't worn off at all, and everything is in perfect working order. This mouse was a good purchase. FEATURES: Ergonomics: This mouse is comfortable and really holds your hand well. My girlfriend often attempts to The side buttons are easily distinguished from one another and are comfortable to use. Adjustable DPI: The adjustable DPI buttons are often useful for gaming. As an example, when playing Overwatch I'll set my DPI rather high when using Junkrat but drop it nice and low for Widowmaker. Or, while playing the Witcher 3, I'll adjust my DPI on the fly if I'm fighting, going through conversation options, or navigating my inventory. Battery Life: I change the batteries on this little guy a few times a year. I can't even tell you how long they last because it's too long to track; it's just not something I ever think about. Logitech bundles the mouse with optional software that will tell you when your battery life is low, as well. It's worth noting here that I [mostly] turn the mouse off when not in use. The mouse is equipped with an energy saving mode that I never use unless my battery begins to die. Sensor: This mouse can be used on MOST surfaces, with very few exceptions. First, the surface must be flat. Dips or bumps will affect tracking. Second, it can't be wet. Moisture can affect the senor. Besides that, I've yet to find a surface the mouse struggles with. I've even used it on fabric furniture arms for gaming, which wasn't ideal due to drag... but the mouse tracked perfectly nonetheless. I'd be interested to know if anyone else has--if you've had issues, leave me a comment. I'm curious. Performance: The mouse has a listed response rate of 2ms. Despite the assertions of many hardcore gamers, they cannot detect lag from a device like this; a wireless mouse is absolutely adequate for gaming. The average human brain has a response ceiling at around 12ms, so claiming one can detect input lag on a 2ms mouse is ludicrous. CONCLUSION: If you want a SOLID gaming mouse that is comfortable, durable, and versatile, that combines outstanding battery life and game-ready performance, I recommend you consider this device. It has never let me down despite the abuse I've leveled against it and I continue to use it to this day. I've had several friends buy them after playing a bit on mine, even when the price ranged between $50-$70. Now at only $40 it's a no-brainer.
