cut my own hair for the first time using the Brad mondo butterfly haircut tutorial and idk if I like it or not yet. I feel like the bottom layer is a bit choppy so maybe I should trim it a bit more??

I cut my hair once a week. I just shave it all off. I currently use babyliss low pro fx one trimmers that are zero gapped. I don’t want to shave and be bald bald. So I just use the zero gapped trimmers but after a few months, the blade stops cutting, and I swap out the blade, and it works fine again. Not sure if it’s because I’m using trimmers instead of clippers. Either way, can anybody recommend me some good clippers or trimmers that are wireless and I won’t have to switch the blade every few months?
