It's their customer service, on paper it's bad ass but from day one out of the box it didn't work and then their support is like no, we're not gonna stand by our product but congrats your our new tech and you get paid in replacement hoses and on off valves. But oh no don't put on a good one you bought, it'll void the warranty. That's their go to statement, "void the warranty" can't even touch it without instructions from my "new boss" at harvest advantage without it voiding the warranty. Sorry guys had to vent, don't be like me, buy the cannacure if your split between the two. If it was a brown box cannacure advertised the best drying system the the world has ever seen they would be closer to the truth than harvest advantage, plus I'd have two for what I spent
