This hot tub is great for the price. There are pros and cons for the 110V, and i fully understood them prior to purchasing this hot tub. One of the cons of replacing my 220V hot tub with this one; i do notice the temperature drop a few degrees if we are in and out of the hot tub over a period of a few hours. The pros outweigh the previously mentioned con, and i was also aware of this con prior to the purchase.  Mayfair also has excellent customer service. This hot tub went on sale 4 days after I purchased. I called wayfair about the sale and it was so simple, i talked to one customer service rep and she took care of it in less than 3 minutes. My account was credited within 3 business days.
