I've been using a MistKing misting systems for 3+ years now, and while you can find a cheaper system that will spray water into a vivarium, you will simply not find a product of this quality anywhere near this price-point. The pumps are extremely robust, the spray nozzles are without equal, and the kits conveniently include everything you could need and more. The timer he uses massively configurable, which you will appreciate more than you think. Add to that the super-easy expandability and some of the most accessible and helpful customer service I've ever experienced, and you have the reasons why I only use MistKing sprayer systems.
