Deciding it was finally time to do something about my non-sly back hair, I decided to try out a product called the "Razorba" from their website (razorba.com). The site itself is decent with testimoneals and what have you. Today I gave it a go. Basically a normal shaving blade including handle is instered into the tip. There are pictures on the website. While it came with a razor I had issues with it due to it only having one blade so I just used my mach3. I imagine that if you were to have short hair or stubble it would have worked fine, but for a single guy with no one to help I had to make due.
I'm not going to lie, it was a pain in the a$$! This was mostly due to not being used to it yet and the air clogging my blade. I suggest you use it in the shower. It did take some getting used to, but the end result was damn nice- a sly back! Without this device I would still have a rug back there so the end product was worth the money spent($30 I believe).
For us single guys this is def an issue so having something to keep us independant of other people's help is def a plus. I would recogmend this product
