Purchased This hot tub almost a year ago and after shipping and delivery I  have only had it installed for 9 months or so and used about 20 times. Out of no where the tub does not reach its max  temperature and not sure exactly why. I have inspected it many times for any obvious clues and tried researching online for possible reasons as to why and have not been able to figure out the issue. Unfortunately I cannot give it a great rating as I am a bit dissapointed in the quality of it. This is definitely one of those “you get what you pay for “ scenarios. I would not recommend.
