Can I filter out 1-3 star reviews on the widget for my website?

Why would I want potential guests to be able to find my 1 and 2 star reviews more easily here than they can on any other platform? Am I missing something?

Also is it possible to limit the review widget to a specific width and height or tell it how many reviews you want to display per page?

Any reviews in OwnerRez that you don't want displayed, you can simply Hide them - check the box to the left in the CRM > Reviews display, and click the Hide button at the top.

Great. Thanks, Ken.
Any way to add a rule to have reviews under a threshold hidden automatically?

No, but that's not a bad idea - why not post it as a suggestion in that forum?
