These are a cheaper version of some I've seen before but they seem well enough made to be useful for light weight things.  It's nice they are compact until you need them.  I plan to use the small one for trash in my motor home and the others to hold magazines or laundry. 
Update:  after using and abusing these for a while they are holding up very well.  I use one for trash in my RV and one to hold stuff in my hall until I have time to put them away.  Very pleased with them.

Pros: Good value, more rugged than they look
Cons: None
