Fantastic product! I used it to convert a 10 gal fish tank for my crested gecko Irwin. I needed custom measurements and communication with the seller was so quick and easy. They did mess up my measurements at first, but sent another one that had correct measurements pretty fast. If you do custom measurement, bare in mind that they will subtract 2mm from the given measurements to make room for silicone. Definitely would recommend - it’s so worth it and the end product is stunning! This was my first time building a vivarium, and for future builds I will definitely be using iHeartGeckos!
