I've only had this for 4 days but, so far it meets or exceeds all my expectations.  It is great value for the price, it seems well made, it works flawlessly so far.  The delivery was on time and seamless.  The traction heater raised the initial temperature of 75 degrees to 102 degrees in about 7 hours.  This replaces my previous softub at half the price with nothing lost in the process other than being somewhat less portable and slightly less powerful jets.
