Ill see what the TS 4 is like. Also they seem slightly to small. Offers a great spot to sit and take shoes on and off. They lasted the balance of the ENTIRE SCHOOL YEAR (2 and a half terms) She can probably wear them again this year, but i like her wearing new stuff first day of school. Diese funktioniert meistens wunderbar, löst aber nicht das obige Problem. That they dry the fastest and stink the least and all the cool kids are wearing them and blah blah blah. Two months ago they quit working completely so I sent them to the "Sony Customer Satisfaction Center" in Laredo Texas. Again, the caveat here is for the price range. For a membrane, RGB gaming keyboard, this must be one of the better ones. Fits foot size the straps are a little big if your food it skinny.
