Amazing I can’t wait to buy more!

Exactly what my growing ball python needed.

I was gifted a free 29 gallon aquarium when I won my ball python in a raffle at a reptile expo and she is growing faster than I expected. This conversion kit gives her all the room she needs and installation was a breeze!

Works like a charm

All 3 orders have arrived in great shape and function as intended. This last order of a 29 gallon conversion arrived super fast! I have 2 10 gallon conversion doors on my 55gallon to create a 4x2x1 and the locktite has managed to hold in a full-grown dumerils boa (arguably the strongest lb for lb in the world) that pushes. They are plenty strong at the 1/8th thickness, but also come in 1/4 if needed. Awesome product if you need to make up a terrestrial enclosure without spending 500+ !!!! Gives you plenty of time to save for that fancy PVC . like I said this is my 3rd purchase and each has been great and are still holding strong. Also they will cut to your specific size if you put the measurements in the notes.

Awesome so far!!

I received the box damaged due to shipping and it even had some extra tape on it to keep it together. The amazing team at I Heart Geckos knows how to safely package your purchase. No scratches or damage at all on the unit.. It is currently installed and awaiting the silicone to completely dry so I can start building out my Leopard geckos new home. Thank you team you are awesome and I love the kit!! Will add some setup photos once it is done.


This product was so easy to install and it fit PERFECTLY into my 20 gal longs ! It’s such a seamless clean finished product and I do plan on getting more for my other tanks ! It was packaged nicely and came super fast too. I ordered on Black Friday and it arrived in less than a week! 10/10
