Bests & Worsts Reviews from Amazon

I've only had it 2 days, but so far has met all my expectations. important things you may want to know: 1. I thought 104 degrees would be too low and even after I got in I didn't feel like it was hot enough, but after a few minutes I found myself relaxed and sweating. After only being in for 10 minutes I got out and just passed out because I was so relaxed. In the end 104 is great and does the job perfectly. 2. The top does not hinge in the middle, however if you don't tuck the inflatable part of the top into the cover elastic then you can just unbuckle half the top, pull out the inflatable and then fold the cover in half and it will keep the heat in (for 1 or 2 person use). 3. I have mine indoors. At first I was worried about humidity and I put it near the window so I could suck it out if i needed to and I was going to purchase weather proof anti mold paint, but the tub doesn't seem to produce enough to justify the purchase. 4. The floor of the tub is not inflatable, but with the included floor mat which is basically just bubble wrap and doesn't seem to have any thermal properties, it does make the floor nice and soft and there's no problem there. You may want to add another layer underneath of a thermal blanket or something to prevent heat loss, as it seems like the floor is the primary loss area. 5. You cannot passively keep the tub at 104. If you increase the temperature above 101 then the heater never turns off and just sucks power like no tomorrow. This causes a 1-2 hour wait to heat for use if you care about running costs. More on that in the next section. Here are the running costs and times: 1. I pay $0.10/kwh for electricity 2. It took 12 hours to heat from 80 to 104, it cost between $3 to heat it. 3. If you leave the temp at 104, the heater will never turn off and it costs $4 a day or around $100 a month. (but don't worry, keep reading) 4. I don't understand why they made it like this, but the heater has a passive mode (it only runs when the temp drops instead of 24/7), HOWEVER, this feature requires a 3 degree buffer and the max temp is 104. So passive mode only activates at 101. So while not using the tub, I set the temp to 101 and it goes into passive mode and only uses the heater when the temp falls below 101 to keep it at or around 101 (I noticed it hangs out around 100). There's good news and bad news. The bad news is that from 100 it takes 1-2 hours to get it back to 104 for use. This 1-2 hour heat up costs about 30 cents and then it costs another 20 cents to keep it at 104 while you're using it. So 50 cents per use, not bad. The good news is that while it's in passive mode, keeping it at 100 24/7 only costs 6 cents a day ($2 a month) So quick cost summary: $4 initial heat up $100 a month to keep at max temp OR $2 a month to keep it at 100 with a 1-2 hour pre-heat before each use $17 a month if you use it once a day
