In sun they will dry alittle tighter. They were willing to give me a full refund because the strap broke. The top and bottom parts both come with 3M tape all ready to go. I cant say the quality was bad because my son cant even use it. The 350 PC set isnt nearly as comfortable and dont block significantly more outside sound than the open ear 373 PC headset does. So far the first BEST ELECTRIC HAIR SHAVER Ive got! My baby is getting bigger and the standing and rocking is putting a strain on it. I think it?s very unfair to make customers pay for a return when the sizes are irregular and not accurate. I might not use it, but it?s always nice to have. Very easy to put together and install on the receiver.
