This is a great product. We use it at our daycare center on 65 children twice a day throughout the summer. It is very effective against mosquitos and we love that it includes the sunblock component. The only problem is that the bottles are TOO SMALL. We need it in large bottles. So much gets wasted because it's hard to get the remaining lotion out of the bottles unless you cut them open. All that plastic is also bad for the environment. We would be much happier if it came in an 8 ounce size or larger. Keep making this product, though. It's a keeper.
