A good alternative to this is the OXO Grip Grips Pro Y peeler. Currently 12.99 W/ prime on amazon so about the same price. Haven't handled the GEFU, but I've owned 2 OXOs now and can report the handle is decently ergonomic, I feel much safer using a Y peeler then a swivel peeler, it comes sharp enough to fly through any peeling job like it isn't there and edge retention seems decent (Got a new one recent, going through peels is less effort then a hot knife through butter, ~4 year old one still works extremely well).
NaftoorThe problem with the OXO is they aren't nearly as sharp and they peel off too much of the skin. You should try these GEFU the next time you can get the universal one. It's like butter compared to the rest I've ever tried.
kitINstLOUISI'll certainly have to give them a shot if I ever get the chance! When we upgraded to the OXOs it was from some ancient dull peeler from the 90s, so it was essentially a light saber by comparison but it definitely makes me interested in doing a head-to-head now!
