Do those cheap bud trimmers work on dry buds?

Hi just wondering how those trimmers work on dry buds. I'll be trimming for the next few days, but I'm thinking about saying fuck it and setting these buds aside and ordering a bud trimmer I saw on eBay for 110$.

Im very picky with my trimming and have not seen a trimmer that does satisfactory work. This includes my girlfriend. Though she's learning.

Lol I'm the same way. I do all the trimming. My soon to be ex never would even try, she sure loves to smoke though...
I'm getting to the point where I don't give a shit anymore. If it could do a decent job and save me all that time I think it might be worth it. I'm definitely going to buy one for future buds, I'm just not sure if I should order one today for the buds I'm on now.
I'll probably order later cause I've already started trimming a few hours ago and am on a role.

Does anyone else ever feel like rumpelstiltskin when your trimming? Weaving hay into gold
