Pros: Comfortable grips, 2 to choose from. Adjustable sensitivity on the fly Adjustable LED colour Nice braided cord that seems strong

Cons: So far none that I can see aside from it forcing a tad bit of discomfort in the wrist, new mouse, takes some getting used to I suppose! We will see.

Overall Review: Being refurbished it came with the interchangable grips a bit...beaten up, only a few little scuffs / indents may have even happened in shipping but honestly doesn't hurt it. Along with that noticed the weight adjustment slot was getting stuck a small bit at first. Seems to have corrected now.

Pros: Amazing audio quality I can definitely pick out some smaller things my other headsets could not pick up. Ease of use (it's a USB headset, not much easier) Mic is by far one of the best I have out of 4 different pairs of headsets I have owned. The buttons for control feel very good. I like the ability to lock out of changing them, along with a mic mute and audio mute buttons. The cord feels really sturdy as well compared to most.

Cons: Bass seems to be highly focused in the left ear piece. As do other sounds despite being set to be equal to both sides in the options. User Interface for headset adjusting is a bit...laggy at times even with top specs. Buttons get stuck and sometimes will repeat as many times as you clicked so be careful. Not much documentation for it either or ability to reset certain things. To apply your settings you have to sit through an audio play through which is also rather tedious. Uncomfortable to wear at first but this is similar with all headsets, this will change in due time.

Overall Review: I had to take one egg off due to the bass being focused more in the left ear. Hoping an RMA can fix this. Overall I think it's great but again with the issue if it's fixed with a simple RMA my rating will most certainly increase on this product.
