Review (3/5): Just my $10 & 99¢..
It can get the job done (keeping whatever is covered dry), but do keep in mind that it is pretty fragile.
If you aren't careful, then you can separate the plastic from the elastic while stretching it out.
It is also on the tighter side. If you have a bigger head or a lot of hair, then you could have some difficulties getting it to cover everything.
The plastic kind of smells like a water balloon (the best way I could explain it).
Nevertheless, there are 200 caps in the packaging (so you should have a decent amount of functional caps to run through).
This product would be ideal if: the plastic was a bit thicker, the bonding of the plastic & elastic was stronger, and the actual cap was wider.
8/25: So far I've had 2/5 pop while using. Will update when necessary.
