i love my spa. i have had it for about 3 months now and have used it almost every night, at first i was confused about what to use as far as chemicals after getting our water tested at our local spa dealership we decided on the frog system. this was a good choice we set them to #4 setting and add shock one a week. i have also removed the filter after about a month and soaked it in vinegar and water overnight which cleaned it up nice. we have this spa located in our garage which also has a heater in it when needed. the temp in the spa stays at temp. not sure how it would hold up outside. i was undecided for about 3 months whether i should make this purchase but when the price dropped down dramatically i had to go for it. THANK YOU WAYFAIR !!!!
