Query: Waste of time, energy, and money!

I really WISH I would have read the majority of these reviews before I made the mistake of purchasing this product. I purchased from local Wal-mart as a treat for myself. Today is the first day I opened the product, and I am most disappointed!It should not be this difficult to relax!Bubbles? Where? I have been waiting several minutes already, and no bubbles!Heat? Again a misrepresentation. The water cooled rather quickly. (I live in Hawaii, so there's no problem with ambient temperature cooling the water.)Water Jet? Well, there is a little water jet, very weak. My Water Pik has a stronger and longer lasting water jet.Massager, Brush, or Pumice Stone? Also very weak. The least amount of pressure and it bogs down.I finally gave up and am now just sitting here with my feet in tepid water.
