When you are forced to buy such a brace that you know in advance you will use for a maximum of 1 1/2 months, then the economic factor may play the biggest role.
I bought this specific brace for 72 € including shipping costs, when similar ones cost over 100 €.
As for the functional part, I have to say that it is very stable, the air chamber tightens in the right places (ankle, heel, and calf). Easy to put on and comfortable, you don't feel any discomfort in any area.
It fastens with 3 independent straps and 2 fixed ones, while inflating and deflating in just a few seconds.
The light color should not scare you, it does not easily stain the plastic parts, they are easily cleaned, and the lining can be removed and washed if necessary.
Very practical and helpful, it helped me stand on my feet again in 4-5 days after leaving the crutches.
