1. Reptile's Best Friend: It provides your reptiles and amphibians with a constant supply of fresh, clean, aerated drinking water. The constant flow of water also raises the humidity level in the glass container. 2. SAFE: Made of hard, non-porous and non-toxic food-grade resin that won't harm your reptiles and is very easy to clean. 3. Durable: Equipped with 2. 5W/110V DC pump, which means its low power and efficient use. There is a 2 year warranty, but as long as the small pump is well maintained there should be no problem. 4.

(1L capacity, we recommend you to clean it once a week. )5. Suction cup: very stable, not easy to be overturned by large reptiles.
