When I saw the "Most Helpful" review was calling this a bad product, I felt a strong counterpoint was in order. After my first child was born, I experimented with just about every DEET-free insect repellent I could get my hands on. Most did not seem to work at all; some seemed to work to a limited degree. This All-Terrain Herbal Armor formula is the ONLY DEET-free repellent which has worked effectively. We still use it year-round in a near-tropical climate, and it seems to protect against mosquitoes, sand flies, and other pests equally well. I cannot recommend this product highly enough.
