You may wanna promise that with "perceived" reliability. Here is my story Hate to be a downer but......first tub A7D (ordered May 2023) had an air-lock that both the dealer nor I could fix. Bullfrog did step up and a second arrived last weekend 🎉(after 3 weeks). We fired it up Monday evening and it was shooting shredded black rubber through all of the jet-packs and the #1 pump / filter has very little water pressure. The dealer this time stepped up and sent a technician out to troubleshoot and repair, however, two new pump replaces later, nada. I have asked the dealer for a full-refund prior to taking any legal action. Let's see how Bullfrog steps-up and refunds the dealer. All in all, these are the deal breakers meaning pumps that do not work along with plugged up plumbing in two models but there is 5 other problems including lighting, jets, switches. for a $15,750 spa, come on. Quality control is sorely lacking at Bullfrog in the summer of 2023. Let's see if their customer service is better. Believe me I love the engineering but the execution in manufacturing and QC is lacking.
