Same here. It's all about the technique.I used Prosaso Pre-Shave for a good while. Swore by it. Thought it was the best thing since sliced bread. Until my technique improved and i got good at using the DE. Then I realized it was a waste of time and money. Didn’t improve my shave at all. I’ve never used any Grooming Dept. product. But a pre-shave of any brand/kind would be last on my list. Same with pre-shave oils. Gimmicks and not necessary IMO.
