Review: Relief from wrist pain - I got instant relief the minute I put these on. Now I am very comfortable and in not so much pain. The product is excellent thank you very much. Love your product.
Review: My ulnar is comfortable, cool and boosted!! - I give this a 1 on a scale of 0-10.....a pain scale that is.... and 4 stars for satisfaction. A longer thumb hole would make it 5 stars. I am still healing and returned to work after my ulna bone kept being a bully to other bones. They also removed my pisiform did ligament debridement and removed a cyst from the heal of my hand. So there was a lot going on and the pain was unbearable. I have tried 4 different braces, kt tape, lidocaine creams and patches in 2 mo I have been back at work and finally this will be my last. I am actually afraid to take it off because it is the only solution I have found that completely quiets the pain.

## Features

- DESIGNED BY MEDICAL PROFESSIONALS —The Comfort Cool Ulnar Booster was specifically engineered for people experiencing pain on the pinkie side of the wrist — including TFCC tears, ECU tendonitis, midcarpal instability, and persistent wrist pain after a fracture. This is not a general wrist brace — it is a targeted solution for a specific problem.
- FOAM INSERT FOR TARGETTED RELIEF — A foam boosting cushion placed over the pisiform helps create a counterforce effect to realign and stabilize the carpal bones while depressing the ulnar head. When worn correctly, you should feel the counterforce on the ulnar (pinkie) side of your wrist.
- TWO ADJUSTABLE COUNTERFORCE STRAPS — Unlike standard single-strap wrist braces, the Ulnar Booster features two fully adjustable straps that wrap in opposite directions around the wrist. This biomechanically correct design helps realign and stabilize the carpal bones and support midcarpal instabilities often caused by ligament damage.
- SOFT, BREATHABLE & SKIN-FRIENDLY — Made from thin 1/16" (2mm) perforated neoprene with a soft terry cloth liner for breathability, wicking, and comfort against sensitive skin. Trimmable for a more personalized fit. Hand washable, air dry.
- SELECT YOUR HAND & SIZE FOR A PERFECT FIT — Available in multiple sizes for both right and left hand orientations. Use our size chart to measure wrist circumference and select the correct combination for a secure, supportive fit where you need it most.

### ⭐ Horrible brace
*by A***R on July 26, 2023*

This brace does not get tight and does not support your wrist in any way. There’s a little foam sticker that they send you. Very cheap. They won’t let you return it either if it doesn’t work.
