Do these have a three prong connection on the back, and which unit EXACTLY am I ordering?

Yes it does accepts 3 prongs and is able to connect with 2 prongs... I had to use it during my recent trip to Europe.

Good question Rick...although I am not tech savvy I will say that there is a port in the side that has a three prong symbol if that means anything to you...sorry I could not be any more help to you.

Yes, the one they shipped to me had a grounded 3 prong plug with about a three foot cord. I have two that are still working under occasional use after several months.Good luck.

There's an attached 3 prong electric cord. I hard wired mine by disconnecting the cord in the interior junction box. This is a great unit, albeit a little loud. Super easy installation.

My unit came with a plug in the back... It is pretty short so you may need a 2 prong extension chord to reach an outlet... Hope this helps.

No, these have the base and the two little contact prongs as shown in the photo. Just plug them in.

Mine has a three prong cord. I am very satisfied with my oven's performance so far.

It is 2 pronged, and yes they are polarized. The wider of the 2 prongs being the neutral as it should be. There is no 3rd prong for ground.

First one I ordered was 3-prong and it stopped working about 2 weeks after I got it. The second one I ordered (same link and everything) through a different seller, was 2-prong :/

It does not have 3 prong plug. How do I know if its UL listed? What does that mean?

Hi Annie. The model I received from the seller came with two prongs. But a lot of these discount adapter listings tend to lump multiple knock-off adapters together.
