I had tried using my old beard trimmer to do some manscaping “down there” and ended up nicking myself bad enough to bleed pretty badly, mainly because the slots on the comb were too far apart.I bought this one based on the reviews. It comes with several fixed-length combs, including one with narrow slots. All of the combs are reversible, so each works for two lengths. I did nick myself once in my nether regions with the narrow-slotted comb on the shorter setting, but it was very minor and user error. You do have to stretch the skin to take the largest folds out and I didn’t in that instance.As a beard trimmer, the included combs are sufficient to keep my beard at the length I like (between 10 and 15mm) using the longest comb.
