Ive had wet bike shoes that required 4 entire timer cycles on this thing, even with the "heat" on (the heat does virtually nothing). I modified this to fit a trike for a customer and it worked out great! But please take my advice and size up. Absolutely a 5/5 product, and thats just the holder. These slippers alleviate a lot of symptoms. I?ve tried many of these single ear buds and this one by FAR lasts hours longer than any others I?ve tried. Its too bad, I really want this headset to work without problems. Theyre all doable as "neutrals" but I dont appreciate "bait and switch" and, therefore, give this purchase 3 stars. In denen Stand, man solle den Schuh eine Nummer größer ordern. These shoes are wider than any shoes I?ve ever seen!
