I am going on 6 months with this piece of machine. Here are my biggest problems with it. It is EXTREMELY LOUD. Though they do advertise it’s very quiet. It’s not. I promise. I can deal with the constant noise, if it’s constant. But it changes noise. It gets loud, quiet, or it makes weird noises. Like it’s about to give up. Second, the pieces are not avail. You have to look, no one knows how to fix them. The instructions manual do not mention ANYTHING about maintenance. Or what type of coolant it uses. When I bought it, I clearly stated and asked what the maintenance was and they told me I didn’t have to, just to clean the filters.
