Review on Secure Your Terrarium with the (3 Pack) Exo Terra Terrarium Cover Clip Set, Small - 2 Clips Each! by Gina Cravalho

Great Product! Easy to put on and take off and very secure. The design is very comfortable unlike other clips I've tried. I use two of these clamps on my pig's 10 gallon tank. I found I only needed 2 tank clamps because there were enough to keep the gas cap tightly closed. I recently tried the rest of the clamps on my 20 gallon tank. They didn't fit. It was very difficult to fully put them on. Unlike my ten gallon tank, I had to apply a lot of pressure to ensure both the lid and lip of the tank snapped into place. They were very difficult to remove and buckled at the bottom. My conclusion is that they are great for a 10 gallon tank or less, but you will need to upgrade to a larger size if you have a larger tank.
