I know these have been knocking around for years, so does anyone have one?

Loads of makes and QVC style shit on Amazon, so want a decent one.

Because I'm on Slimming World plan I basically spend and inordinate amount of time cutting my fruit and veg etc and think this would really save me some time over the course of a week/month etc.

Any brand recommendations?

I use a potato chipper now, and throw them in an actifry, fucking fantastic and easy!
