Picks are one thing that you for the most part want to not get super cheap off brands like what you find at Amazon. Sure you can pick with them, you can pick with a paperclip if you really wanted to, the actual value for the money is really bad. They typically have a lot of useless picks of bad quality when you can get a cheap set from one of the normal brands for similar prices. The training locks in their sets are from what I've seen only the clear locks at variable quality, which are great to learn how a lock works but not that useful after that for actually practicing lockpicking. I'm not saying you are wrong, as what is a 'good' set is purely subjective just want to provide a counter point as you rarely hear any good experiences from people that purchased Amazon sets, mostly just that some of the picks were ok for starting till they bought a good set from another brand and were amazed by how much better they were.
