I have really narrow shoulders and I'm constantly dealing with bra straps slipping off, so this product was a godsend! It keeps my bra straps up, and makes me feel more secure. Plus, the racer back style is flattering and useful for wearing under certain tops.
However, I feel that the converter strap could have been much longer. Although it is adjustable, I have found that I need to adjust it to its maximum length just to get it to work, and even so I could still do with more length to ensure improved comfort. I have a small back, so it makes me wonder how anyone with a larger back would manage with how short the max length of the converter is.
Overall though I am pleased with this product, but it could be improved.
