Query: A piece of junk

Even after reading all the negative comments, I was dumb enough to order thistrimmer...Please save your money...The blades will not lock in place. The littlehook on the locking mechanism broke off with my first try to lock the blade inplace...The sharp blades can be very dangerous.I have purchased many items from Amazon...It is hard to believe they wouldallow this piece of junk to be listed on their website...
