This is the second time I have purchased these.  I liked the idea so I ordered a size that should have fit the first time, but it was so big the arms looked ridiculous.  It's been quite a while ago, so I thought I would give them another chance.  I ordered the next size down.  This time the arms and chest are really tight!  My weight has not changed.  In my opinion, this product is a waste of time and money.
