Query: No Good

I purchased one of these back in November. I put brand new batteries in the correct places, and it would not turn on. I was able to exchange it for a new one. This one did not work at first, but after I shook it in frustration, it actually turned on. However, it only worked twice before refusing to turn on ever again. I recently took it to a battery store and they told me I had purchased good batteries, and even checked them (and said that they still had plenty of power).I will not be purchasing this again.
