Query: good plate, but

It is a good B.O.B item, I have in the past wrote a bad review of this item, but after using it a few times it does work, but it's not as thick as the one I used back in the early 90's while on active duty.But if you write a bad report these people will email, and harass you until you change your review of the item. So I 'm not going to say the product is bad, because it's not, but the company is not very professional at all.
