WE also got our tub with in the last week. And I agree,we have used more than our share of test strips. But we are learning together which is good. Why we didn't buy a tub a few years back I'll never know because we missed out all of these years. Now I know there were some posts about wearing a suit or no suit. Well last night We were sitting there with no light on and my wife says boy this sure does feel nice and I got the suit threw right in my face. Well, she was right. The no suit thing is great!!!! Just a great time sitting in there each time and after driving 12 hours a day like I do it really helps on the stiffness of the legs and back.
