The only reason its 4 stars is because when ever the power has a glitch(flashes off & back on) the fuse to the pump blows. It is a very easy fix but annoying because it rains often in FL. The fuses cost me $3.50 for a 4 pack. I was able to call a retailer to trouble shoot & learn how to change it. Now, we cut the power when not in use which is usually during the week. It holds heat very well. So, it doesn't take long to heat up. Initial heat up was approximately 15hrs The hot tub itself is awesome. Love the "plug & play" aspect. No electrical work. The LED lights are pretty cool at night & the waterfall is soothing. The jets are comfortable...not harsh. Its drains from the bottom, so, its simple to change your water when needed. It fits on our lanai.  Additional coverage wasn't needed. It comes with a sturdy cover that is rain proof. No issues from our HOA because we didnt have to do any structural changes. We can move it later to a different location when ready.  We love it!
