Agreed. Went on the search for knife sharpening tools on Amazon, and quickly discovered that some looked like copies of others. The copies would look identical in the pictures, and have a huge amount of 5 star reviews. Then as I drilled into it I saw a large amount of problem reports.

Decided to just not buy anything from Amazon that day.

(Have found them really useful for other things though. And Prime Shipping in Australia is great.)
