I've had a Mist King for about 18 months now. Bought the smaller unit with the zip drip valve. I've since upgraded to 9 misters running in 3 cages and its working like a champ. I try to use R.O. water but honestly I have mostly used tap water and all my nozzles work fine even the 18 month old ones.
Just got a mistking. been using it for about a week. works like a charm. alot of people on this forum like aquazamp as well. aquazamp is made in the USA. either way you get a good product
I have a mist king with a rain dome. I made it myself out of a i gallon water bottle. You just cut it in half and attach the mist nozzle to the bottom of the bottle. Then set the bottle upside down on the top of the cage. It works just like a rain dome. when I was shopping for a mister the mist king had the best timer hands down. That was what I was looking for.
This has been discussed over and over, with a quick search you will find more reading than you want.
I have a Mist King and it has worked great for me, no problems, timer works GREAT etc. I really think they are both great systems with only minor differences and you can't go wrong with either of them...pick one buy it and don't look back
