Promising review: “These things are fantastic. Every once in a while you acquire a product people refer to as a ‘holy grail’ because there’s no way it could really be made better and it solves all your problems. This is one of those products for me. I have spent my entire life wondering why razors don’t come with good travel cases. I travel all the time and my sister-in-law who also travels introduced me to these when I forgot my razor. Before the end of the trip, I had bought three and a full pack of replacements because they aren’t that expensive and they work fantastically.
“First of all the shave is great, which is surprising. Second of all, even though it’s got that tiny circular handle, it’s surprisingly ergonomic and easy to hold onto. I find it easier to use than a normal razor so I use it at home as well. Third of all, the cases are perfectly sized to slide into pretty much any bag, and the refills come individually packaged in such a way that makes it easy to toss a refill in with it if you are going for a long trip. Fourth, the case has really good ventilation, and you can tell that they were designed to dry out.” —INeedAPublicNameIGuess
