Yet at first I was quite wary because the wrist guard is flexible enough to touch and you wonder what it will be able to protect ... But once harnessed the wrist as shown in the pictures in the description Amazon product (because no user manual, good at the same time, it is certainly not rocket science!), I was amazed by maintaining and holding it provides, even during sudden movements. Only potential inconvenience noted, almost obligation to finger loop (with a bit of contortion, it can be removed once protects tight) that can interfere if one is not accustomed, especially for certain sports .. .
Aside from that, the material (100% synthetic course!) Seems rather resistant, and scratch for adjusting the size protects the wrist is fully satisfactory in terms of pure adherence. Occasionally practicing squash, said protecting fully met my expectations and was perfectly able to relieve the tensions inherent in this sport. So very good, very reasonably priced.
