    Reviews for the M7

    by Bullfrog Spas

    5 Stars for Design, Service and Performance. You will not be disappointed with an M7. It simply has made my life better.

    Love our M7

    Jake B.

    We did a huge amount of research before choosing our M7 and we love it! Bullfrog is high quality, style, and Innovation. We went through the whole back and forth of 'lounger or no lounger' and with our M7 we got the best of both. Each seat is unique in height and shape- with two of the seats also having leg supports with jets so they are sort of loungers. Because each seat is a little different and the jet packs can be easily moved around- all our friends and family can have their 'just right' spa spot- the M7 is both beautiful and versatile!

    Ease of the display controls, overall modern look and the adjustable Jet Packs

    Top notch Hot Tub

    Walter M.

    Hands down the best purchase we made for our new home. The bullfrog experience from retailer to service and support has been amazing. I'm thrilled with the massage in the jet packs, the size of the M7 is ideal. As for styling, the look of the slick M7 bucks the norm in the best possible way.

    This spa is everything that was promised! We love it and the flexibility that you have choosing and using the jet packs.Only negative was the wait (4 months) but it was worth it!

    Love it!

    I found the manufacturer lacking quality control . I bought the m7. The outside panels were hard to take off and near impossible to replace. Still waiting after 4+ weeks. The doughnuts that held the jet packs was faulty. A jet pack didn't work correctly. The display is faulty. . Etc etc
    I can't recommend this brand. It's a lot of money and I think it's fair to expect a better product.

    Spa is very nice, love the all the upgrades. I do have a issue with the display getting wet very often and turning the spa on and off because of it.

    Spa is very nice, love

    I have one of the first M7 spas and while the layout and size is great, there are serious issues with the engineering and build quality. To start the design of the trim strips and panels is awful. i have had at least three parts break trying to reinstall the panels and trim. Even the crew that originally set up the spa had to use a rubber mallet to get them to pop in place and often they pop back out. second the new clear headrest for the jetpacks look good with the LED lights, but the clear plastic latches must be made of cheap plastic or badly designed, 5 of the 6 headrests have broken, and they are designed to allow for easy swapping of the jet packs. Lastly on both the original water fill and now on a second drain and refill, the spa displays a start up error - no flow condition. the first time i had to wait two days for the service guy to come bleed the lines. The second time I had to do it myself, luckily i had watched the tech. Unfortunately due to the design I suspect it will happen at each time.
    I would avoid the M series until they work out these issues.
    Finally, Bullfrog customer service is non existent for a $26K spa. A Kia car costing much less comes with far superior customer service.

    Great concept, terrible execution

    Simon H.

    We have had a variety of issues with things not working. Want to like the spa. Love the look. Hoping everything will work and provide us with years of time in the spa.

    We have had a variety

    I paid more for a Bullfrog spa expecting higher quality and service. Disappointed in both. The spa looks great but I miss my old spa- the glitz just isn't there and response was very delayed with my issues. Ultimately they were resolved, but I hate to go through a number of folks to get a responsible response. It's a beautiful spa but not above average.
