Took longer than I expected to receive it, but maybe Jeff Bezos has made us all monsters. ;o) This purchase was to "re-buy" our Shake Weights because we moved & haven't been able to find our old ones in storage ....can't be without 'em! They WORK! And it's hard to find them now, so I'm very grateful that you offer them for sale (and don't get too greedy with the price). VERY grateful. Thank you!
