Would totally recommend this for camping and home use! I can’t usually cook a decent steak on frying pan in kitchen but my steaks on this are awesome. Have also cooked pikelets, bacon and eggs, toasted sandwiches and burgers. Saves such a mess in the kitchen!

I've been using this cooker camping and I love it. It's versatile, portable and easy to clean. Very happy with my purchase.

The unit arrived and required some assembly - So far, so good. 
Base unit ✅ feet ✅ drip plate ✅ regulator ✅ hot plate ✅ feet screws 5 ? Stud screws 5 ? Washers 5 ? Nuts 3!
Fortunately, I found something with an M6 thread I could use that had a large enough diameter.
Try to fit the studs to the plate... 3 go in fine. One required thread cleaning of the hole.

Fit gas... Lights fine.

Take it camping. There's a bit of a breeze. A shield had to be placed around the unit to get the plate to heat up. I was expecting a hot plate for cooking a steak. It was barely adequate with the shielding. Took forever to cook a sausage.

The thing weighed a ton and couldn't pack as a unit for transport: Regulator hose sticking out the side, studs protruding from inverted hot plate...

I would not recommend this product.

Design changes I would (and probably will) make: remove levelling from the hot plate. Make the feet on the base unit adjust for levelling.
Without studs protruding from the hot plate, it could be seated better using just simple cap screws. Incorporate high temp rubber grommets on location holes to minimise heat transfer and also rattling during transport.
Mount hose so it can be coiled, or find another solution.
If no case provided for the unit, make a handle that wraps around and secures everything in place.
Find some way to secure the drip tray & prevent it rattling during transport.
Incorporate some form of draught excluder.

Like I said. I would not recommend this product.
