We bought the J-495 a month ago after wet testing a similar model. The jet action is powerful, the lighting is just right and not over bearing, the stereo sounds good and works great and we like that it has 3 separate pumps for jets which gives all jets adequate volume and pressure. The center dome jets is one of our favorite items plus it helps you support yourself when the back jets are on so you don’t fly off the seat. Please NOTE the J-495 needs 60A service and Jacuzzi does not deliver the hot tub to allow for 60A operation, you MUST change the DIP settings on the control board for 60A operation in order to allow all operations to work correctly. See the manual to know what DIP settings to use. Also, I recommend you set the temp 1 degree higher than you want it because the heat will not engage again until it falls 2 degrees below the set temp and in the winter time (2 degrees is huge in water) it will not keep up with the cover off since the J-495 is so large so start the tub out higher than you want it. Lastly, the delivery crew were excellent and placed the tub exactly where and how I wanted it and installed the removable cover assembly perfectly. The access door panel trim was coming loose and Jacuzzi customer service mailed me replacement screws immediately. The one thing we wish was different is turning on the waterfall, you have to open a valve which is too close to the edge border of the hot tub which does not give clearance for manly fingers to open the valve easily, than closing it is just as hard, especially with wet fingers. This needs to be changed so you can turn the waterfall on and off from the control panel. Other than that issue we love this hot tub.
