They will work but not without a few issues. The seam is exposed to damage, the nozzle seals fall out and need to be glued in, and two of the four nozzles drip fuel from the junction where the flexible portion attaches to the can. In one of the four cans, the air vent is misshapen blocking the pump nozzle making it hard to fill.
Most of these issues are easily fixed, but the exposed weld seams only time will tell.
Overall, a good deal at less than half the cost of wavian.
