Very sturdy,  made with sturdy materials.  Throws out a lot of heat.  This product really surprised me as far as how much heat it throws out and so cool looking!  will not tip over easily like the other propane patio heaters.  I'm ordering another one for my patio.

Pros: Bang for the buck.  Heats up a big area,  will not knock over easily,  
Cons: If the glass tube gets wet it will break.
