What is the opinion of Reddit about the
Wahl Groomsman Cord/Cordless Beard Trimming kit for Mustaches, Hair, Nose Hair, and Light Detailing and Grooming with Bonus Wet/Dry Electric Nose Trimmer – Model 5623?

Just bought this one, only used it once. Lots of them sold, dirt cheap, high ratings and it worked well on my first use. Sorry for the Amazon link, it’s how I got it, though. It meets your criteria.

Look up Beard Trimmers, my man! You can adjust the length of the trimmers on most of them, so you’ll be able to dial in your sweet beard.

I don’t have this one, but Wahl makes good products. It’s cheap too, so maybe a good one to start with! https://www.amazon.com/dp/B07B9Z8LV7/ref=cm_sw_r_cp_api_i_t-7sFb23A9KF7
