As an inventor myself (www.coolfoot.biz, www.bac-rac.com) I was intrigued with the concept of the Shoo-away. My wife and I love eating meals outside which is possible much of the time here in sunny California. Unfortunately, flies often drive us back inside...no more, these things are wonderful. They are silent, seem to run a very long time on one battery pack (x2 AA's) and guess what, they work! Since we've used them, we can enjoy our meals outside. We see the flies and I'm sure they see our yummy food, but they never venture closer than several feet away from our Shoo-away. 5 stars for sure! I'm a bike-packer and I'm going to find a place for one of these in my kit!
