"[This review was collected as part of a promotion.] I tested these plaster on a couple of areas. On my index finger the plaster seemed to stick well and didn’t wriggle about too much. It held up fairly well upon washing my hands but still peeled, no worse than other waterproof plasters. The small round plaster i tried on my arm, and this was terrible, it hardly stuck at all, I would say it stayed in place for around 2 minutes so I didn’t get change to test is water resistance. It was almost as though any hair at all stopped it sticking - and my arm is naturally not that hairy as a woman! I don’t think it would work very well on an area with hair. I think these need far more adhesive so be worthwhile."
