First off I want to say that I've been to the other barber supplies and it was not a pleasant experience. Very shady environment and aggressive sale tactics.
However, my experience at Rubinov's has been completely different. Joe and Mike (the owners) spent almost an hour showing me products as well as recommending razors and blades. I bought a couple of shave sets today for last minute Christmas gifts as well a new razor and aftershave for myself. This is a hidden gem in Arizona and I'm glad I found them.
