I use this product to hold my Pro Rep jelly pot's safe and secure off the floor of my vivariums, so I can place the holder at the right height on the vivarium glass using the suckers to suit the needs of my arboreal lizards, and to stop any contamination from the vivarium substrate.
This is a great little holder that sticks very well to the plastic on a insect keeper. Stops the jelly tipping over and getting covered in substrate.
Not used them yet but very good quality
Just what I needed for my baby crested Gecko
