+ looks great both with LED on and off
+ simple and comfortable design (claw/fingertip grip)
+ no drivers
+ thin braided cable which is by far the best cable ive used
+ hasnt malfunctioned once at low sens in cs:go at 450 dpi.
+ balanced weight distribution
+ super lightweight
+ LED colours can be locked at different levels. so if you want bright red, you can lock it at that point when it changes, or have it less bright, etc.
- build quality is so-so due to the whole mouse having to light up. no moving parts, but you can tell it doesn't have a durable shell like other mice.
- gets dirty fast and much more so than other mice. it's fine if you have LEDs active, which I assume is 80% of the reason you'd buy it in the first place.
- you can feel the i-rocks logo on the left side which might annoy some
- high LOD
