Question: can this be converted to natural gas
Document: I love the fact that it can be taken anywhere, and we're planning to bring it camping once the weather gets warmer. Light to carry and easy to clean, we've totally been converted from charcoal grilling with this little grill! My husband says it's so easy to grill on it he wants to cook outside all the time with it, and I don't mind that one bit.
The portable gas grill was a gift and our grandson loved it. he is college age and has a small patio at his apartment.
the reason i gave it 4star is because when i made burgers the grease build up on it very quick because of its size other than that great gas grill
Love the adaptability of this grill! Great for the patio, tailgate, or beach! Only needs a small gas canister, so very portable.
We use it camping. Great space saver and  grills very well. It uses less gas than my coleman grill. Woud recomend it.
As a single guy I use the grill almost nightly.Heats up fast and easy on the gas.And if need be very easy to take it with me.
very portable and easy to use. I hooked up a 5lb gas tank when cooking in my backyard and i usethe canistr type propane when on the road
Compact, attractive, well-built, starts easily...and an added plus:  No Assembly required! You'll be glad you purchased this portable gas grill.
This grill is very portable, light and very easy to use. I have always been "afraid" of gas grills but this one is a breeze and cooks well! I highly recommend it.
Only used it twice and now cannot get flame. I cleaned propane hose,  can hear gas but still no flame that a small wind would blow out. At a loss!
Answer: yes
