Like everyone else, this being a site unseen purchase of something I knew little about (110 vs 220), I have been extremely pleased.  It does take about 2 days to heat up and another few hours to adjust the chemical level, but after that it works exceptionally great!

Since we have set it up, our temps have been about 50-55 during the day and 35-40 at night.  We set our temp to 104 and can get in for about an hour and it may be 102 when we get out.  You are so hot at that point, you really will not notice the difference at all.

I would highly recommend this tub to any of my friends who were looking for a Hot Tub for their home.

PS: The only recommendation I would have is that when you set the tub up the first time, before you put water in it, consider placing some shower grip pads on the seats, we find that with the jets on, you slide around a little too easy!  Not that big of a deal, just something I wish I had done.  I will the first time I drain the tub.
