Bests & Worsts Reviews from Amazon

I bought these snaps at the local craft store and then realized I didn't have the pliers to apply. I came home and read the reviews that made me regret the purchase. Unfortulately, I didn't have time to return to store etc, so I ordered the pliers on amazon. Ordered with prime and Saturday shipping, came on time and well packaged. First few snaps and I almost ruined my project:-(, I then started youtubing instructions as project had to be done tonight. Found one very informative video from the KAM company showing the difference between shanks. Stated on the instructions shipped in packaging says already preloaded with the shank and die for size 20. Well when watching youtube video they showed how to pull off clear rubber and check shank size and lo and behold the larger shank was inappropriately loaded. Die size was 20 as stated in paper work but not the shank. Changed shank and immediately applied 5 snaps with no problems. 4 stars because product works well, but crappy instructions!!!! I very rarely write reviews, but thought this one might help someone out there.
