A large amount of reptiles and amphibians kept in captivity come from regions with extremely high humidity and maintaining this is often essential to their health and part of your responsibility in offering proper care to your animal. Mistking is second to none- a must have for anyone with tropical tree boas and frogs. The set-up is quick and easy and a year down the road I have not had one issue even after letting the tank run dry on several occasions. Fantastic equipment and incredibly good after sales service which often is the true quality test for any company. I started off with the Ultimate Pack as a Christmas present to myself - which was a really good choice and have since expanded to additional nozzels. It's a bit like SONOS the music system - it is a bit of out-lay but so worth it and once you have it you see it is money well spent, after that you get addicted to expanding your system!
