One works fine but the other timer counts down in seconds not minutes so is useless. Easy to attach to roof and holds a lot of stuff. Seller not responding to return labels I tried pretty much everyone of the ear bud sizes they offered but ultimately each one felt uncomfortable in some way (too big, too small, fell out too easily) and I have to constantly fight in putting these back into my ears as they fall out very easily. It seems to have gotten better. :-( it looks to be a piece for the drawer so I should be able to still use it over all which is why I gave it 2 stars instead if 1. I have about 7 pair and these 2pair are like trying to walk on a board. Really comfortable so it is probably worth the price. They are very comfortable to me. These shoes were better than I was expecting.
