The Chirp unit works very well. It is easy to use, and I have found it really eases my back pain as well as the pain in my IT bands.

Life changing relief available whenever I need it. Amazing and affordable. Thank you.

I love my Chirp Halo. Easy to use. Best of all no wires to get tangled up.

Great product. Second time buying it. This time for a different location. Love the sand color and extra rollers!! Please add backlighting to the remote in the next version!!!!

No other TENs unit could come close to what this thing does. Could not be happier with this purchase
