Delivery was two weeks early and went smoothly. Set up was a lot easier than I expected. It took about 45 minutes to fill. We knew to fill through filter so had no issues with air lock. Water increased about 5 degrees an hour on initial fill.. Chemicals don't come with spa but knew from other reviews to have on hand when delivered. Less than 24 hours after delivery we were enjoying our new spa. Water temp was perfect and even with jets on high only lost 2 degrees over the extended time we were in spa and quickly regained when we got out So far so good..
Update. This has been a dream. I am in the spa every day rain or shine. Temperature stays true. Filter runs automatically and shuts off when reaches proper temperature. We have not seen increase in power Bill's over winter. I have changed water and filters with zero issues
