I received a free sample of überlube with my most recent purchase, and having never heard of the brand before, decided to look it up. From their website, Uber is a sexual lubricant, sports lubricant, and also a hair product. Crazy, I know, so I decided to test some of the company's claims. I suffer with extremely frizzy hair, so that's what I tried it on first. It tamed it right down without giving my hair the oily, wet look so many products do. Fascinated, but no longer possessing enough Uberlube to test it out in a real-world sex situation, I decided to give it the finger friction test. It held up admirably. I couldn't get it to wear out on my fingers, they slid together smoothly. Next, I tried the same thing under running water. It still held up and kept my fingers nice and lubricated. It also lacks any unpleasant aromas, isn't sticky or tacky, and washes off easily with soap and water. I fully intend to buy more of this product.
