Review Content Incredible! Having had wrist surgery and continuing with physical therapy for the past two years, this product provides instant relief every time I wear it. It is simple to use and operate and am certain it works well in conjunction with my rehab. Incredible Relief Having endured a total Row Carpectomy, and sadly, unsuccessfully, this device provides me great relief and since it is not plugged into the wall, I can use it "on the go". It is working jointly with my PT. I absolutely recommend this product to anyone suffering chronic wrist pain, incredible! w/ a thinner battery, itll get 5 STARS! It is quite good for a travel aid. I found it compact, easy to use, and well designed. What if the product used a thinner battery similar to thats in a cell phone? It could cut down the bulky size and reduce the weight. It would be more comfortable for small wrists. Excellent pain reliever. 1)I have RA and with very inflammed and sore wrists, Putting the battery in place was a painful job. I needed help. 2)If your a small person, the thumb opening is pretty large. I wish they had 2 size wrist bands and a Flatter Battery. 3) I LOVE HOW IT WORKS. After all that above. I am still thrilled to have this. I wish I could have one for each wrist. The battery life is pretty good and charges easy. I will travel with this AND sit at home with it. Easy to use. My image was sharper than this product. I ordered this due to a critical wrist injury and subsequent surgery. I could not get the controller inserted in the wrist wrap. At all. It is bulky and with the addition of the plug, I found it impossible to insert the controller/battery. I will admit that I have limited use of my left wrist, but surely a company such as this could have designed the pouch better. Either bigger to allow easy insertion or a smaller controller. Now I have to go through the effort of packing (again with limited use of wrist) and returning the product. My image of this product was sharper than the actual device.
