I purchased the 7010 hybrid system from them in may. Their product is excellent. Their communication in my case was terrible. Their website order form mis-calculated the number of tubs I was supposed to receive and they charged me for 16 extra tubs. In august, after not being able to get in touch with them by phone, email, or facebook, I asked for my money back. Magically the next day everything shipped. I ordered the 8 inch heat panel upgrade and they sent me the standard panels. Then they sent me 8 inch heat panels that were too long. On the third try, I got the right heat panels. I also ended up with a lot of extra parts that I didn't need. They told me to keep them or throw them out. How can that be cost effective to just give away components? Anyway, when I did get in touch with people they were super nice, and their product is the best or as good as anyone in the business in my opinion. I don't know if their business kicked up because of covid or they're always like that, but they seemed disorganized to say the least.
