-This keyboard can sync with other Corsair LED lit devices to have a continuous pattern. Poor rating though because my mic dropped out of the stand and the black wire broke away. SpotyPal device also works very well for helping me to locate my cell phone when Im home alone and cant find it. Whatever material they are, I doubt they will ever wear out. The sole is cushy and is about 1/2 inch. great buy so I am now buying a pair in the other color! Great for plantars fasciitis and pregant swollen feet. I was really pleased with the quality of this garment compared to some other sports wear i have bought on amazon. The mid & table is a slightly forward sound which is nice and really lends itself to electronica and especially live recording! It worked great and was easy to install.
