Had been looking at this as a replacement for an adjustable razor I'd been using for years and finally purchased it here on Amazon. Wow! What a difference! Very nice quality, the blades lock in securely and are perfectly aligned. Did not use the included blades as I've read they are not the best quality so used my trusted Astra platinum. Great shave and zero irritation! Great thing about this razor is if you do not hold it at the 30 degree angle it was designed for it will not shave but best of all it will not cut you! Great razor for beginners or experienced shavers. FIVE STARS!

Great razor! Recommend 10/10

Size: 1 Count (Pack of 1), Color: Rose Gold Razor

Love this razor. Previously had a Solara razor, this was way cheaper and honestly feels like better quality. However, important note… do not take it with you if you are flying with a carry on! It was an innocent mistake, I didn’t think anything of it but because it’s a single, removable blade, you cannot take it through TSA

Great little razor!

Good product! It’s pretty easy to use, it has some heft to it, the blades are sharp, can’t complain especially for the price.

A Quality All-Purpose/Beginner's Razor

Size: 1 Count (Pack of 1), Color: Black Razor

These Zomchi razors tend to have pretty good ratings, but a lot of the reviews and interest in them is from women. As someone who has been shaving with a safety razor for many years now, it's awesome to see women getting into safety razors, but girls shave differently from us guys so I wanted to write a review as a guy. *I will say it bluntly right here, if you are a guy or girl in the market for a safety razor, or are on the fence about trying one, buy this Zomchi razor right now. You won't regret it, and neither will your wallet. This razor is great value for money. Beautiful design with nice machining. Construction is very sturdy and even the threads that screw into the head into are top quality. On top of that, the razor has a black coating that will prevent rust later down the road and protect the longevity of the razor. Shaving my face, this razor gave me a really smooth, close, quick shave with a feather brand blade. I wasn't having to come back and make extra passes. It cut sideburns easily and got the difficult areas other razors tended to nick. If you try the Zomchi blades it comes with and you don't like them, there are so many other brands available with different characteristics. With the right blade this razor will be amazing for everyone. -Long story short, if you are looking for a quality razor at an affordable price that simply gets the job done, this is the razor for you.
