Been using a Quinetics puller for 20+ years. Use it on a concrete floor, as well as a 4x4 under the deep freezer. No problems yet.
Now, if you want a story about a primer and a vacum cleaner, I've got one. Had a 3'x4' piece of rug I kept to stand on next to the reloading bench. It was looking pretty nasty, so bought down the vacum cleaner, which was, a Hoover bag type, with bristle's and beaters. Didn't take 3 seconds of vacumming, and I found a primer. When it exploded, I don't know who moved faster, me, or my dog. Never seen an 80+lb German Shepard/Rotwieller mix run up a set of basement stairs so fast.
The bag was smoking, as it set the dog hair on fire, and I had to take it off and get it outside rather quickly. Now, I sweep the floor with a broom. gypsyman
