I feel safe using OFF! I have used this brand for over 10 years. It is really an amazing brand that is out there. Now I really use it for my son. He loves being outside and playing. The thing about him is he gets hives from literally everything and mosquitos are the worst where we live. With that being said we really have to use candles and and everything to try and keep them at bay. As soon as he gets outs they attack him instantly. It is a matter minutes and he would be covered. With using off, they stay away from him. He can play outside and we will not have to worry about him getting ate up. This is great for us especially when during the summers family is coming in and there are a lot of BBQs and get togethers. I also know that there are a lot of bug sprays that have a smell to them and they are supposed to be unscented. Well this one is really unscented.
