Product review (2 stars): The actual stove unit is nice, the flame pattern and force is a bit ...
Update: this thing is a fire hazard. It catches on fire regularly. I finally stopped trying to fix leaks and threw it out.

You have to remove rubber o-ring on regulator for it to work with propane bottles in USA. The actual stove unit is nice, the flame pattern and force is a bit weak and uneven but gets the job done and I couldn't ask for more for the money. Make sure to tighten clamps around the fittings on the cheap hose. Even with tightened clamps, propane will slowly leak. You have to turn off tank in between use.
