The shoulder wrap fit very poorly and no amount of tightening and adjusting helped. As a result, many of those therapeutic lights didn't even make contact with my shoulder to provide whatever relief they were supposed to.
And I certainly didn't appreciate taking a 20% hit on the refund for the return shipping. You should at least provide a return shipping label if your products don't work out for a customer.
It shouldn't be a surprise to you that I won't be trying any more of your products.
