Seems to be pretty good deal, Ive had one similar for over three years and no issues, at least it would be a good spare...12 bucks including shipping...
I've been using a similar $7 Chinese knockoff stove for 4 years now with zero issues. The piezo ignition still works too. Fits nicely in my Snow Peak titanium 28 oz pot along with a small fuel canister. I admit, I was skeptical at first, but it's proved to be a great value.
