This tub is much better than this advertisement will lead you to believe. I was hesitant to buy it because there is a lack of information on Overstock.
Here is an actual link to the specific tub. It is a Laguna Bay X6

The tub name is "81 Jet" This does not mean that there are 81 individual jets. The foot blaster contains 14 "jets" and there are 3 or 4 seven hole "jets" around the bottom. This is still plenty of jets. Probably 45-50 separate jets.
The large switch on the top diverts water either to the foot blaster (awesome by the way) or to the lounger. The middle range is a blend of both.
The foot blaster is not shown in the picture on Overstock.
The picture and description show a 4 button control panel. Mine came with a much nicer control unit.
There is a waterfall directly above the filter. It is controlled by the knob nearest it. Waterfall is adjustable from off to full force. I like it on, but gently. There is a filter included.
Shipping was very fast. The website says that it will leave the warehouse in 1 to 10 days, and that shipping will take between 1 and 6 weeks. That gives a delivery window of 8 days to 52 days from the day that you order it! Mine arrived in about two weeks. Only one delivery brought it; but between the two of us we got it exactly where I want it. Everything I read called for 30" space to each wall. I wanted it lined up with a bay window that we have so I cut the space a little short on one side, at a ~25" gap. The side panels come off completely, and I'm relatively thin; 25" is enough for me.
Installing the electricity to the tub was harder than I thought it should be. It's a simple design, red, black, white, ground; but difficult in actual execution. I ended up taking apart the "weatherpack" connection so that I could get the wires to the right location. The spa calls for 6/3 wire, which is pretty thick. It seems that the screw connectors are slightly too small. I removed 2 strands of wire from the stripped area (.5" each)
I've used the hot tub almost daily since it arrived. Make sure that any clothing worn in the hot tub is washed a second time, WITHOUT soap. I had to change the water after about a week because of the huge amount of soap bubbles in it. Draining the hot tub is not explained in the instructions. There is a hose connection on the bottom of the tub with a cap on it. Removing the cap doesn't start the flow of water. The connection must be pulled out in order to start the flow of water. Remove the cap, connect a water hose, THEN pull the connection out about 2 inches. I found this out only after I drained it using a sump pump. The sump pump did an amazing job and I will continue draining it this way. The whole tub was pumped out in about 6 minutes. After refilling the tub, it took over 12 hours to heat the water from 53F to 101F, at ~60F outside temperature. This is 50% longer than the 8 hours the instruction say to allow.
I wish the lighting was a little brighter. The second pump was a little loud. There are instructions on the link above on the Laguna Bay Spa website on how to bleed the pump. That helped quiet it down a little.
I'm using a SpaFrog with Bromine and Minerals. It seems to do a good job keeping the tub nice.
My electric bill has increased $28 from last month. I assume future months will be less. This month I heated 350 gallons of water from mid 50F, two times. In the future I'll drain the tub only once every three of four months.
I hope this helps people considering this purchase.
