The press and snap are great, I go throu about 1 pair a year., Hugo also set a few thousand snaps before they go bad, the shaft wears on the aluminium housing and they begin to stick.. for normal use, they would last alifetime.
Best.price was at perfect fit MC Donald online....
Keep looking. I just bought a Fas-snap benchtop machine off Craigslist for $100. Brand new, came with 11 new dies. The machine and dies are worth about $500.
I tried it with my stock of snaps, and it works fine. Fasnap
Those will drive you crazy. If you do not want to spend the money for a professional tool you are better off with just the plain cup and set type. I know it says not recommended for stainless, but if you are looking to change a snap or two every now and then they will work fine.
