I love the quality of this item. Pros:It locks securely. It is adjustable to take your glasses and not get in trouble for them being too big or small. The arms are super strong -- I can put on my eyeglasses, sit down, watch television, then lean back against the arms. Cons: Mine came without a manual. There was no paper contact with where it goes together. And no instruction sheet.
Good Review

The premise could have been interesting if fleshed out better. There was no back ground given. You never understand where the characters come from. Why are they on that island for all these years? What happens to them? There is a constant thread of horror going on with them so I found it confusing. It seemed like half way in or less before their encounter and rescue by an unknown person. They don't know who he/she really is, but some events follow up later on. All this information feels forced.
Bad review

I bought two sets. The first set had a problem with one of the earphones. After trying all kinds of tricks and tweaks on my iPod to make them work, I've decided it is not worth returning them. So, after much research, ordered another. This pair sounds fine. The problems are they fall out too easily from time to time. Sometimes when I have some weight in one ear, other times not. They also seem very thin and cheap. Not a whole lot here at $20 per pair.
