I bought it because the descriptions state it is 110volt. Turns out, it is 220volt. I had to go extra step to install 220volt outlet. That took extra time but eventually wad going to need 220 anyway. Otherwise, I would have returned for a 110volt. That said, I am happy with the unit. This is Day 1.
