I have been extremely impressed with the quality of the system and the incredible customer service from Marty. I use the Ultimate system in a 9x14 greenhouse and it keeps my orchids cool and humid. I had a problem with the power supply after three months, contacted Marty last Friday evening, he promised to send it out on Monday. I received it Tuesday (I live in Saskatchewan) and it worked perfectly. Well done Marty! This is a company you can trust that has an excellent product.
