I didn't see this thread so I created my own. This product is great. I have only used one razor after getting a sample from GD. One additional benefit: I am getting more shaves with the blade. So far I am on my 10th shave on a GEM PTFE which is a few more than I usually get.
No worries brother. Not a problem at all for me. The more threads, the better. And yes blade life is a potential residual benefit. I have also experienced an extra shave or two from my blades as well....
Happy shaves....
