Ironically, I havent been able to lose this one but will buy another when I do. Basic Green/Blue light but won’t keep you up at night because of being so bright. No slippage anywhere 😀 and straps not sticking out or flopping around after adjustment as with some brands. It’s not - and the fake leather cut up my feet. Somehow this mouse I purchased in February 2017 has already dug its own grave. I was afraid that to get what I needed, Id have to pay $120 - $175 for a blue tooth ear thingy, and look like one of those idiots walking around with them hanging off there ear. I ordered size 12D and they are commodious, not tight at all. Not a great material. They look really comfy, looks like you can wear them outside because they have a nice soul, and they look super warm too, but it makes no difference if you cant get them on. As several reviewers have said, they lack any cushion at all, no heal cushion, no arch support, no padding on the strap, none of that.
