This is an awesome item! i would recommend it to anyone! Its a little expensive though! When using it make sure to always wear tennis shoes! My grandmother freaks out when going out to mow or vacuum with out wearing tennis shoes. she always say you could cut a toe off!  which is true. the best time to use this item is later in the evening when its not to hot. drink plenty of water! stay hydrated! if your thirsty then its to late!
