I am now 50 years old and I have a lot of pains that I did not have when I was 30.
My body is older! And we ski a lot in the winter.
I have gotten to try a few of the Bullfrog new Jet packs that are targeted at the neck area, the last one was not available when I first purchased my spa. I liked the minineck blaster I think that is what it is called.
The Jet pak has a life time warrantee against leaking.
At 6'-1'', I do not have to do anyting but sit down or use the lounge seat. This spa is great for me!
With hundreds of different manufactures I am sure you will find what is best for you.
I like the Bullfrog.
Probably what I like the best is the dealer. He seems to try and keep me happy with new product information and services.
