they are useless!! [SEP] I bought 3 brands of dress-shield and I tried these last. These were thinner (like the 2nd brand) and I understand the manufacturer not wanting a bulky shield but when they are this thin, they are useless!!!!!!!!! People who buy these, sweat and as such a paper thin shield is a waste of time, money and  embarrassment. If you perspire, avoid these. If you just want to avoid deodorant marks on your clothes, good enough!
