I have to agree. Maybe I'm just old and fumble fingers but I have lost as many caps that I have put on with any capper that I bought, and I have bought all that I have seen for sale.................A piece of leather, punch holes........works as good as anything. BUT the best way is to do it by hand...........Again that is just me.I prefer a leather capper. Mechanical things tend to always break down on me. I like the KISS method.
