Great brace, great customer service
Another model that I originally wanted is unfortunately not being manufactured any longer. The customer service people contacted me and explained how this brace was the recommended substitution and went over all of the brace's features so that I felt comfortable getting into the Fullforce instead. They were very helpful. The Fullforce arrived and I have been wearing it now for two weeks and it's both comfortable and supportive. Very pleased with my purchase.

Works great for skiing.
I had an ACL reconstruction earlier this year. I've used this brace skiing twice now and it works great. Even forget that it's there at times. Saw other people mention the brace sliding down your leg - haven't had this issue yet. Overall, I'm happy with the purchase.

Brace does a good job protecting my knee
The brace provides excellent ACL stability. I had a left ACL tear and a surgical repair in 2014. I wore a CTi custom ACL brace for lateral/cutting sports for a couple of years until I re-ruptured my ACL last year. I then transitioned to sports that did not require a brace. In the last year, I started doing self defense karate and went without a brace until early this year when I ruptured my right Achilles. Unfortunately,the left knee was doing a lot of the work during recovery and it became unstable again. Although my old CTI brace still fit and worked, I decided to buy a newer technology brace, assuming it would be a better fit and work to my benefit. I was right. What a great brace! It is comfortable and easy to use. You might also consider some sort of under the brace sleeve protection (neoprene or legging) until your skin adjusts to the pressure points.

My doctor recommended this brace for me after my ACL surgery healed. I feel safe wearing it and my knee can handle running and jumping alot easier with it on. Recommended.

Fits my short height perfectly.
I am short 5'4" so I went with the Short calf length and it fits me perfectly. I will be using it for soccer and wakeboarding water activity.

A great brace to return to action
I got this brace to replace an over the counter brace that I purchased at Big 5. I am a soccer referee who has had a problem with my left knee for over 30 years. A few years ago I went to see an orthopedist who told me that I had no cartilage left in my knee. However, I was not prescribed a custom brace. I recently learned that I could get a good brace without it being doctor prescribed and started doing research. I have found that the Donjoy FullForce Knee Brace was just what the doctor ordered. I have used it now for over two weeks and just love it. My knee is much happier and I feel 10 years younger as I am running around the soccer field.

FullForce helped my fooball season
Wore this brace during football while I had a torn ACL and it felt almost as if I didn't have a torn ACL. This brace was everything and more than what I expected it to be like. Thanks DME-Direct for allowing me to finish my senior season of football with this Donjoy FullForce.
