Not to mention he admitted that the previous owners had the water chemistry all screwed up.
I have a Bullfrog 331 and it is a great spa for me, I have called bullfrog directly with questions the dealer could not answer, they were polite and very helpful, and told me to feel free to call them anytime.
I love mine even more since I went from soft soak to chlorine.
Do not badmouth Bullfrog because you tried to save a few bucks and got screwed.
I move my jetpacks quite often just to get a different feel so don't speak for everyone when you say people do not move them around.
Edit,
I would not consider this a review of a bullfrog spa it is someone who did not do thier homework and expects bullfrog to pay for it.
