I am slightly disappointed that the neck massage doesn’t do my shoulder blades as well as I thought, it must be user error or the design is for specific heights. The neck massage stopped working after not even 10 massages. I’ve only had it for a few weeks. I’m in the process of placing a warranty claim. When I contacted Renpho to lodge a warranty claim their customer service was exceptional, they were happy to help. I had to send them a video to show that it wasnt working and within 24 hours a decision was made to replace the entire Neck and Back massage at no extra cost! It is one of the best customer service experiences I have had when lodging a warranty claim. The Massage is now working well.
