These are a fantastic option if you need some crutches for a couple months to get you through an injury. My ortho dr. Says they are much more comfortable to use! This type crutch has been used in europe for the past 20 years.

Can be loosened with a phillips-head screwdriver and a pair of pliers or a spanner.

Only downside is that the arm cuff grips are on the large size. It is not the end of the world but it gets more annoying as you use them more. Hope they'll last that long, but skeptical about the cuffs.

Forearm cuffs are far too wide even for an adult. The cuff is not adjustable! Company admits they don't make an adjustable cuff.

The arm cuffs are way too big, which makes the forearm crutch far less effective. The grips are extremely uncomfortable and can't be replaced. The rubber covering the arm supports rip off or the rivets pop.

These are the worst i have ever purchased in over 30 years. It needs to beable to stand by itself it keeps falling which i can't bend to get. It's generally very flimsy. They're cheap; alas, they're also worthless.
