Review on Zilla Heavy-Duty Screen Retention Clips by Alquino Scarwin

They work great! I have a ball python and it ran away 3 times before I got it. Now he can't get out at all. They are very easy to use and the first set I bought still works great years later. If you have a large snake or tank I would recommend buying 2 sets (4 clips total). I currently have a narrow/long 55 gallon tank and the Optimus is a good mid-sized snake so a clip on each end works great (they go in the middle). Although you can easily make 2 on each side.
