One said: “Absolutely love this product, I read the reviews before purchasing and was a little apprehensive when buying but didn’t need to worry as this product is worth its weight in gold, I really wish I’d found it earlier. “It’s amazing that this little bottle has given me a bit of my confidence back . I really wished I’d found it sooner, as looking back over the years all the clothes that have been ruined by horrible yellow marks, the amount of times I’d have to change 3/4 times a day, clothes I’ve wanted to buy but never did because I knew they were no good for me in the summer. “I’ve finally been able to move away from black tops in the summer months. “So if you’re reading the reviews like I did and see the good and the bad… please you have nothing to lose by giving it a go. “I know it may not work for everyone but it has for me and also my friend who I instantly recommended it to. This little bottle is a total game changer .” One mum posted: “My teenage son was having problems with getting sweat patches under his arms and ruining his shirts, not to mention the embarrassment he felt when with his friends. ” This deodorant has worked brilliantly , kept his under arms completely dry and kept his clothes sweat free. And even though it’s unfragranced we haven’t noticed any odour at all. The bottle does look very small, however it is still half full after weeks and weeks or use. So we will be repurchasing.” A third added: “This product really works very well. I’ve tried all sorts of the same or similar roll on and none have come close. I’d recommend this to anyone.” However, another mum was disappointed: “Really disappointed that unfortunately this has not worked for my daughter. She followed the instructions very carefully but the underarms of her school shirt were soaking with sweat again today.” Amazon describes the deodorant as follows : “The ultimate level of protection from sweat and odour. This antiperspirant deodorant for men and women is specially formulated to reduce wetness, stop odours, and eliminate discomfort and embarrassment. “Apply at night before bed just once or twice per week, ensuring good coverage.
