Helped with carpal tunnel syndrome.
I’ve been suffering from carpal tunnel for a couple of years now and my chiropractor suggested that I try this product. I started with as little as 6 seconds per day and slowly work my way up the strength level. After a week of using it, I could feel the pain in my hand significantly lessened! I was amazed as I am not used to having strength in my hand. I definitely recommend this product."

It literally saved my hand!
I finally had my carpal tunnel surgery, but due to COVID physical therapy was not possible. After a while, I noticed I had no grip or strength in my hand. When I found this product I use it non-stop. I even throw it in my handbag so that I could use it anywhere. Now, my hand has improved by over 75%, and I can open jars and perform daily tasks that I have taken for granted. This product literally saved my hand!"

Helped me manage my pain & discomfort.
It helps me immensely with pain in my hand. I am an automotive technician and work in a repetitive motion with my hands all day long. At the end of each day, it would cause me a lot of pain. Using this product has helped me manage pain and discomfort! It’s wonderful to have such a simple yet powerful tool that helps me stay at my job and make a living. Thank you Koprez!"

How to use the wrist trainer?
Finger Trainer:
1. Place the loops over each finger.
2. Start with your fingertips close together.
3. Slowly spread the fingers apart, hold for 3 seconds, then relax them slowly.
Grip Strengthener:
Crushing – Place the Grip Strengthener in the palm of your hand. Use the base of your palm and the middle of your fingers to exert force inwards – a crushing action.
Extension – Place the tips of all five fingers into the hand Grip Strengthener. Spread your fingers evenly out in an extending action. As you push your fingers further outwards, you should feel greater resistance from the Grip Strengthener.
Pinching – Hold the Grip Strengthener with the tips of your fingers. Squeeze the Grip Strengthener with a pinching action. You may intensify this exercise by using just two or three fingers. This exercise will be relatively harder compared to the Crushing and Extension grip-training techniques.
