3: The sound quality is fantastic. Another drawback is the software. Ill keep it as I have already sent back one damaged bench from a different company. Is pretty BUT every time i walk it makes a sound like is deflating ( like air sound) sooooo annoying. This product outperforms its pink counterpart in every way. My granddaughter says like all of this brand its like walking on clouded. I didn’t want to spend the big bucks to buy another pair. My 95 year old mom loves these. My only issue was putting it in the wall. Good, easy to make recipes that have cheap easy to find ingredients.
