Query: Epic Fail

I bought this due to the really good reviews. I was awfully disappointed when I received the actual product. I used it on my roommate who didn't even scream, but just asked what one earth was on her night stand. The second time I used it I got a scream that only caught the (failed) victim off guard for a mere millisecond. I highly recommend everyont not to buy this product if your intention is to scare people.
