Query: too bad, but it just doesn't last

I bought this item, but had to return it because it broke the first time I did more than take a 30 second spin on it. Instead I bought this one:GSI Quality Electronic Figure Trimmer Balance Musical Twist Board - LCD Screen Displays Count Of Twists, Time, Fat And Calories Burned - For Diet, Weight Loss And Keeping FitThe GSI was much better and I recommend it. See my review of that product.
