Mistking is the best! I've purchase two of their pumps now and countless nozzles. Every time the pump turns on I get a smile because it happens without me! When I set the timer and can walk away, knowing my animals will be hydrated and happy, that makes for a satisfied customer. Marty has always responded promptly and provided excellent support in my "time of trouble." The whole system is well designed and has MANY applications. The problem is...my animal collection is no longer limited by water delivery!
