Here is a short review from Trailspace-
review

What do you want to compare it to? There are literally dozens of stoves of all types. Primus is one of the classic stove brands. This one looks like it would work just fine.

Brand new and free? Buy a canister and see how it works. If you like the idea of a canister stove, don't worry about comparing it to something else; they all basically work the same.

If you don't want it, give it to a local Boy Scout troop or similar organization. I'm sure they are always looking for donated gear.
