Title: 2 PRONG - Ungrounded unit...shorts out!!
Review: Description says "Three prong grounded plug". This is not accurate. It is a 2-prong ungrounded unit that shorts out when submerged in the pre-heated oil. I debated purchasing this item due to the negative reviews. I am a retired industrial maintenance tech and yes I followed the directions. Since they were calling for blizzard conditions I thought it would be worth the risk. I installed it in my (warmed up) tractor and plugged the unit in. The following day after the storm subsided, I went out to see if it was working. It was ice cold and I could see by the discoloration that it had indeed heated up and shorted out. I ordered a replacement and I am hoping that I will get the proper 3-PRONG grounded unit.Just an update: Amazon sent me a replacement. It also was another ungrounded heater. However, they changed the description of the unit to a 2 prong, ungrounded heater. I returned the unit to Amazon. Once again, great customer service.
