Uncomfortable and doesn't seem it works

I'll give 2 stars to this product just because it seems that is well made, no cheap material.

However is crazy uncomfortable to wear, unless you wear it loose. But if you wear it loose, it kinda become useless as its like you aren't wearing anything.

When wore tight, it just feel like you are wearin a backpack, but it doesn't really help me having a straight posture. You received two so I used together with my husband and he had the same impression as me. So I don't feel like recommending such products to help with your posture or back problem, to me doesn't seem that efficient.
