Review on Titanium Microneedle Roller For Beard And Hair Growth - 540 Needles, Home Use Body Roller With Storage Case by Craig Kimball

I use this to roll my crown and hairline. After a few uses, it started making a loud squeak with every motion. I used medical-grade alcohol to sanitize before and after every use. Not sure if it's just my roller or a common issue with this brand. Easy to use, can't really be hard to use one of these I imagine. The case it comes in is bad, though. Can't really put it away easily now because the top won't stay on, so I leave it off.I would recommend this roller based on functionality alone, with no issues in that regard.
