I was pleased to do business with Alonzo's Oil. Their Beard Oil/Shave Oil is a good product. I wanted to wait until I'd used it a number of times, to give a fair evaluation. I usually shave in the shower, so my face is always washed and steamy. Whether I use Alonzo's alone, or as a pre-shave under lather, I get a close smooth shave, both with a typical multi-blade or with a shavette straight razor.
My only suggestion would be that Alonzo's come clean with customers, and publicize that the Beard Oil is the *same* stuff as the Shave Oil, just with two different labels. People might be surprised, even skeptical, that one can use an oil for shaving, but if they just try it, they'll see. Don't hide it; brag on it.
Any regular shaver should at least get the small 2 oz. bottle and see for themselves.
