I ordered the Trueback, and because of a glitch in their website the c/o part of the address was omitted. The OTHER office at the address didn't recognize my name, so UPS returned it to Morcent. They refunded what I had paid, less shipping and handling. Eventually I reordered the device and this time I received it. It is very hard plastic and very uncomfortable - especially with a sore back, so I returned it. They sent my refund to the right address, again without the c/o so I never rec'd the check. I emailed them and after several months they re-issued the check. I was out about $45 for the first and 2nd S&H charges and the cost of returning it. My back didn't get any benefit from the product.
