Opinions on vulv trimmer/shaver products

what are your opinions on these devices? I'm looking to fix my public hair regularly. I got some laser sessions years ago but loosing the effect and I'm not planning on getting more atm. Therefore, my hair is growing faster. I use scissors currently but I barely fix the "anterior vulva commissure"

I have used razors before on the bikini area but I get extremely itchy. Same issue with my armpits I try to shave them as few as I can to avoid irritation as I can but its difficult during summer it prevents me from using sleeveless outfits frequently.

I just want the safest option for my labia under $40. Plus wondering... Does this model shaves or trims? is it good or bad?

I saw good comments on a Philips, I just want to double check on that one and see if there's more options.
