My first thought is ʞɔnɟ yeah! Those things are a pain in the ass to peel! I have the knife cuts to prove it!
My second, third and fourth thoughts are, SCAM!!!
Tried finding videos of them in actual use and this was about all I could come up with
If they ACTUALLY work like that, I am going to owe you big time! Thank you!
If they are, as I suspect, just a gimmick… I’m gonna remember who sicced them on me! 
Lol, I always peeled them with my thumbnails and still have regrets. Grandpa used his penknife.
This thing is cheap enough to give it a try. I hope it works!
Oh, you mean real Chestnuts. I was on a totally different tack. Phew!

This is NUTS!!!
someone had to say it…
OK… I don’t know what in the hell a CHETNET is
but… so… they work… kinda sorta…
The scoring part works GREAT. That not only makes scoring easier, but helps the inner skin slip off easier.
The peeling part, though… 
I’m pretty sure that that is a defect with the user more so than the tool itself. We boil ours nuts (
) - or more accurately, pressure cook them - instead of roasting them. We like them softer than roasting gets them, but that makes the peeling part of this tool harder to use. I think if we were to roast them, it’d probably work out just fine.
I guess you’re off the hook
I had bought one for my Mama, too, but it’s not going to help her enough to even bother, so… I guess someone is going to get one in a random woot box one of these days
