The shipping was very quick, was well wrapped, and the red light therapy machine is high quality. I read elsewhere that it can help lymphedema, which I have on my leg and foot, so purchased the machine for that. I have only been using it for a week and have not seen an improvement yet, which is fine, as I expect it will take time. I'm pleased with the quality of this machine and the good service from the company, and if the red light therapy helps my lymphedema then wonderful. If not, it was worth the try.
