Query: Waste of time

I just bought this at Target today. I had to wait 25 minutes to get it because THEY didnt even have it on the shelves (nor a spot for it anywhere in the store). Target had to get it from the back. I should have taken the hint. This product sucks. My 10 dollar shaver does a better job at cutting my hair.All the good reviews here must be made by the Mangroomer folks themselves...
