Very good, it helps a lot, you shouldn't use it for more than 4 hours a day! Only a little under the armpits it cuts...

It does provide support, although not perfectly, but at least satisfactorily.. The worst in terms of fit.. until you put it on, it gets tangled at the back and one end sticks to the other.. It can't be worn without a shirt or with a tank top because it presses uncomfortably under the armpits, even the largest size.

Generally, don't expect miracles.. it won't correct the slight kyphosis that we may develop throughout the day.. but when you do, for example, tasks that require a lot of standing or the opposite, it can help for a few hours

The strap is very helpful for the body to maintain the correct posture in every position. Even using it for one hour a day is enough, as its job is to create the habit of proper body posture - a type of "memory" for the body. I appreciate that physical exercise works additively, so along with the strap, issues like hunching and back pain can be resolved. Ideal for use in office work and household chores. Logically, it would also be very helpful for pregnant women, although it would be preferable for a lady to tell us this. The only negative is that from the first month of use, wear and tear on the strap (fraying) is observed, but within reasonable limits, due to the velcro (hook and loop) and its friction with the rest of the strap. This is also the reason I didn't give it fewer stars.

Very mediocre opinion, it pulls slightly but does not provide satisfactory support from one point onward. After a while, it becomes uncomfortable in the armpit area.

I bought it for better posture and to avoid slouching at my workplace! It has good grip and it's easy to put on!!

It didn't suit me at all because whenever I wear it, my hands go numb from the pressure it applies, even though I don't tighten it too much. I wouldn't recommend it.

Product of quite good quality and at a relatively good price. The material is quite elastic and covers the upper part of the back, so it does not hold it perfectly stable. For someone who has a serious posture problem, it may not be suitable because it does not prevent slouching or leaning forward. What it actually does is remind us, due to the light resistance it provides, to stretch our back backwards and hold it straight more comfortably. It is a body posture aid, it does not determine the posture.

This product does not perform well. It is better to choose something more compact that covers and tightens the entire back. I do not recommend it.
