Mantis 175 APU – Discontinued

Mantis

Their address comes back as  “Weldmation” a company that was previously licensed to manufacture Comfort Master but was unable to meet their obligations. As always, buyer beware. It is typically the consumer who ends up in the middle of the legal battles that are sure to come.

These things like a Comfort Master knock-off. I tried to get a hold of them several times and got the run-around. I can’t find anyone who has actually bought one. If you have please post here I want to know.

I have no complaints about the Mantis, its been running strong for the past year. I’ve only performed simple maintenance on it my self. My comfort level is very important especially with the time I spend on the road. Before I purchased my unit I spent a lot of time researching similar products, this was the best product I could find for my money. I’ll be cranking the heat up this winter to keep warm and toasty!
