Rose M.: The therapist said it would help strengthen my left wrist and possibly avoid surgery. It did not help me, but the wrist felt better for a few hours after using it.

Matt Robinson: I wish I had bought this instead of paying for physical therapy (where they recommended this to me). Within days the constant pain was gone and within weeks I was ready to buy a stronger version to continue strengthening the muscle.

Lisa: This can also be used like signal lights when held at the ends. The bounce may give additional stimulation
to nerves and muscles. Could there be a longer, 3' bar to exercise back muscles and legs?

Amazon Customer: There are many flexible resistance bars on the market. While I haven't tried them all, I do really like Serenilite's product. Other manfacturers put a slight pebbly texture on their bars which would appear to give them better grip, but actually make them more slippery in my experience. Serenilite has a shiny smooth surface which makes them almost feel tacky. My hands have a much easier time maintaining a good grip on these.
I wanted to give a shout out to their customer service. I ordered a bar directly from them because Amazon was out of stock. There was a problem with the order, unfortunately. But customer service responded to my email inquiry within hours and offered a very satisfactory resolution to my problem. I was very impressed.
Good products and good customer support - I will happily buy Serenilite products again.
