I would have several concerns over Bullfrog but the biggest on in your area would be that in order for that system to work you have a "trunk line" feeding the jetpacks along the top of the shell where the shell tapers into the cabinet. This line is more likely to fail than any other part of the spa due to the fact that it has movable unions at several points. The problem here is that it has less insulation and is harder to get to than any other piece of plumbing in the spa. My estimate is that you won't see a failure in that hose until the month after the warranty runs out! You also won't get nearly the performance overall in that system as you will most other systems due to the fact that you need to share several manifold processes in the same line.
My husband and I are really excited about buying our first spa....we do want to make a smart purchase.So anyone who can comment on my questions -- jump in please!1. Like I said, we are easily influenced by bells and whistles so we thought the Bullfrog was fun and interesting. But I hear a lot of negative talk about this brand. Can you tell me what the specific issues with this brand are? What are its drawbacks and problems?2. What is the best round spa for 5-6 people?3. Does anyone have suggestions or knowledge of good dealers here in Minnesota? 4. Are there brands we should avoid because of our FREEZING COLD winters? (We're planning on installing our spa in a new 3-season porch ... but there are still dreadful windchills here.)Nice to meet you all ... and thanks in advance for any info you wanna pass along.Red
