They look like they cost a lot more than they do. When these earpieces arrived I was very excited. As time went on using this mouse it became more and more evident that the left side is actually slightly convex under the thumb buttons and the grip width is on the wider side ? significantly wider than the G403. it takes a little bit of time getting to learn the phone but I like it. The first is that the back strap is a piece of solid plastic with nylon webbing and Velcro. Even Walmart shoes have them at this price. Still not thrilled about the design, but the Crocs customer service was A+++! She loves her new ?whippers? as she calls them and wears them around the house nearly every day. I was shocked it didnt gape a ton under the arms (which is normally what happens with many dresses). Walking and general head movement can make them slide around.
