Big Buddy propane heater

This model heater arrived in perfect condition well wrapped and was here in less than 24 hrs with all the features I wanted which were in sparse supply with a blower fan built-in. Driver was very professional and a great communicator. Great job Walmart!

Mr Buddy Heater

the heater and accessories arrived promptly with no shipping charges. the heater works as advertised, and the convenience of using the hose to connect to a 20 LB tank is more than worth the price. the heater will be used as heat on the patio and is an important emergency backup. this heater works as well as my first Mr. Heater still working after 15 years.
