we had the product on a holiday in Kenya in use. The 50 ml have good enough for two people for 14 days, in which we have made only arms and legs. Large-area, the product should not be used anyway. The application works very quickly and easily. In the first minute, it smells a bit but the smell dissipates very quickly. The effect is very good - one night we had forgotten the application and it shows immediately. Additionally the pump spray We had, What was even more comfortable to use and is also very good in the effect. At the end we still had plenty left over - I think a bottle would have been enough thick.
