After years of having lemon grass planted in my yard, growing nearly out of control and a pain to manage, I now have a product that is small, smells the same, is inconspicuous and is the perfect thing to have around for summer picnics, evening playtime, camping trips, hunting trips, and so much more. Well worth the money spent!
