I'm looking for a compatible big button remote for a Comcast box RNG110/ Part Code/B4043432900

My client has a few that she likes, but I can't find out if they will work for her and Comcast has been less than helpful in providing accurate information.

Here are the ones we're looking at:

Any feedback would be very appreciated!

Thank you.
