Ordered a swim spa from this manufacturer in a parking lot at a show. Gave them $3,500 down payment. My delivery date was 90 days out. Followed up to firm up delivery date 90 days later and was told it would be another 4 weeks. Followed up on that at 8 weeks later, told another 3-4 weeks. After questioning the honesty of this transaction Company abruptly cancelled my order against my wishes. Do not trust this company, when they can't deliver they make a quick exit. I had a new patio and retaining wall installed, had electrical work done to prepare for this spa that I will now never get!! I have spent thousands of dollars in preparation work for nothing.
