It's ok. We'll see how long this lasts...

The design of this is such that you can't simply push the canister down into the slots in the arms. Instead, you have to start by resting the fuel canister into the slots on two of the arms, and then wrapping the 3rd arm around to it's open position, sliding the edge of the can into the slot on that arm. Then it "should" lock the other two into place.
However, as another reviewer mentioned, the plastic is very stiff. This means that in order to insert the fuel canister into the stabilizer, you are putting a huge amount of torsion on the two small pins that hold the plastic arms together. Jthis also happens when removing it. Just getting the can in and out of the stabilizer twice loosened those pins up significantly on mine, which doesn't bode well for longevity.
Once the can is properly set in, it stabilizes the can and stove nicely. It works for now (after some awkward maneuvering), but I'm afraid that it will weaken at the pivot points and possibly break after more uses.
