Hi, barber here. Don’t buy a cordless trimmer. They are trash and don’t last. I have experimented with top barber quality cordless versions of their classics and they are garbage and you can’t fix them. The best trimmer on the market is the Andis t-trimmer. All parts are easily replaceable and you can have them serviced by Andis. For anyone reading this who is also wondering about clippers, Andis Masters.
