Question: What are the snaps made of brass, stainless, or regular steel?
Document: The tool works OK on the brass snaps that were included in the kit, but it would not crimp stainless steel snaps at all. The stainless material is too hard.
I purchased the snap kit to replace the snaps on my worn out tonneau cover. The snaps held fine until the first time I removed the cover. All the snaps pulled through. The snaps are made of thin brass and are not very heavy duty.
I love this thing. I had other kits that you put the snap in a metal cup and hit it. The snaps always popped off. This kit is made well and crimps them perfectly. No more problems with them coming apart. I would give it 6 stars if I could.
This kit seems to be made up of very high quality components. The case is excellent and is easy to open and close. The pliers are very well made and secure the snaps to my canvas very securely. Note the kit is for attaching the snaps to canvas only; there are no screws for attaching snaps to rails or other materials. If you need do to that I recommend the "Set of 25 Snap Button Screw-In Studs."
What a piece of JUNK put in 5 snaps in the handle squeezed together
The snaps are a  little on the light weight side but so far they have held up nicely.
Kit allows you to install button snaps into canvas or other thick fabric. It works as excepted, no complaints here.
Works as described ,no problems ,same size snaps as the jacket I had to fix .This kit was less than having to take it in to be fixed .
Very quick shipping and seems to be a quality product for a reasonable price. A must have for putting snaps in difficult places.
Very handy and easy to use. It is a compact little kit that I store on my boat in case one of my snaps break.
Answer: yes
