they make several models. the F31 is the replacement for the F3. They modified the early models to fix some issues.

Yes. Without doing a careful comparison, it seems the same. Was there something specific you were concerned about?

You'll have to check with the item (if ordered) that YOU got from what was advertised on Amazon. Hopefully the two will be the same. If not, I'd consider my alternatives...either to keep or return the item.

Yes it looks exactly like the one I bought and installed in mine. Works very well, easy to install, and you can't find a better price.

I believe it is just a difference in color. But by the way it does work well and I have had no issues with the unit... Good luck!!!

It never occured to me, but mine too is not like the images on amazon. I am very happy with mine and recommend it but it does not match the images.

looks the same, however, be careful when tightening the screw the unit is plastic and will break if to tight.
