I did a lot of homework before buying this nifty little spa. Measuring and such for the perfect fit for all my needs, well, gotta say...it paid off! This little spa is exactly what I needed!!! First off, the delivery men were very friendly and helpful putting it where needed (for I am handicapped). After getting it prepped and filled to my surprise it fired right up and continued to pump until it reached desired temperature...took about 11 hrs. Most spas I have owned had to have one or both pumps primed so this was great! Now if you are buying this spa for four people I will say it will be a little cramped...unless you all 5'6" or smaller! Or 2 adults and 2 kids! But seriously, for the money and space...it's a great little spa!
