Product review (4 stars): Sturdy, but VERY tight latch (You can fix by bending it)
Does the job just fine, seems very tough and sturdy.  The only downside is that the part of the lid that serves as the latch is VERY tight, and it takes a lot of force to open it up, so much that you have to be careful not to injure your fingers when it finally pops loose.

This can be rectified though by placing the container on a hard surface, and then leaning on the cage and bending it in a little bit, or you could try and bend the latch part outwards.  Just bend it into shape and it should be fine.  It takes some heavy pressure to bend it too, though, as this is a tough little cage.

I'm taking one star off for this because someone with weaker or sore hands will not be able to get it open.  If you have hands like that, you can have a friend bend it into shape for you, but if you need something easy out of the box, best to try another product.
