I bought this a few weeks ago after extensively researching patio heaters. It has wheels for easy movement; the recommended type of starter; an anti-tipping feature to shut it off it falls over; the ability to add sand at the bottom to make it less likely to tip, variable temperature control, and east of assembly. Love it and we've enjoyed on our patio on a few low-60 degree evenings and it's just right to take the chill off.
