Arrived on a timely basis, well packaged. Set up immediately. 1 lb. Propane. It was fairly easy. Once I realized The input would turn to make this an easy process. I did experience an issue with the electronic start. I had inserted the battery and all seemed well but would not function. I called customer service and was very pleased with quick response. The problem with the electronic ignition was a user error. I had installed the battery with the negative toward the spring on the cap. Come to find out it goes in the other way. Once the change was made I immediately had electronic ignition.I set this up in my shop and it is pretty cold here. Set on high and it began to heat quickly. As with many others, The built-in fan is pretty weak in distributing. I will be setting up another fan behind to direct the air flow better. The manual leaved a bit to be desired. It certainly covers all potential hazards and I'm sure is very helpful to first-time propane users. The manual should have explained about installing electronic battery. Second, there was no indication as to whether it required a c or d battery for the fan. Just looking at it. I figured it was D. That worked. The other issue is to describe plug needed for the fan if someone does not want to use the batteries.I am in the process of preparing to hook up a 20 lb bottle and only used the 1 lb to test out the efficacy of The heater. At this time, I can say I am pleased with itUpdate. One of The regulators for the 1 lb propane bottles was bad. A machining issue. I contacted Mr. Buddy heater and they indicated to return the item or go through Amazon. I chose to go through Amazon and return the item without any problem and 3 days later had the new one. The new one does not have this issue. I can only say that between Mr. Buddy heater and Amazon. I am now satisfied. The new one has no issue with either one of the regulators. I can say that it has heated up my shop very quickly to a comfortable temperature.
