I had never heard of the Imperial brand before, but the price of the pre-shave oil was cheaper than The Art of Shaving, so I thought I would give it a try.
It's okay. It's definitely not the worst brand I've used, but not the best. The smell is okay, but I have to use quite a bit (3 medicine droppers' worth) in order to have a good shave - anything smaller than that portion is like shaving dry. From reading the other reviews, it sounds like I might have a formula that's been watered down significantly.
I'll put it this way: I'm okay with this product, but I wouldn't go out of my way to buy this again.
