1 year update.
Still love the Wiakiki Elite and I use it year round. Winter I keep it at 102 and summer I dont need to heat it at all since it does see some sun during the day (in MD).
We've had no problems at all. I replace the smart chlor cartridge every 3-4 weeks and mineral cartridge every 3 months. I usually shock the hot tub every week or so (not sure if that is overkill). Will need to replace both filters soon but if you did a better job than me of washing the filters out regularly you may get some more life.
Really not a bad thing I can say about it.
Since I've had this Wiakiki Elite, I've tried a Barefoot spa, another jacuzzi, and a Sundance and I can hands down say I made the right decision for me.
And I love my lounge and foot blasters. Some people dont like the lounge seat but I find it does a great job on my calf muscles.
Hope that helps anyone looking to get an artesian/tropic seas.
