It should load really close to the same speed. It uses a different javascript slider library with more options. I've debated on removing the Normal slider, but in some rare cases the normal does work a little better for people.
Okay, sounds like we have it narrowed down. I'll do some testing and get a fix out.
Out of curiosity, are the bugs still there if you switch over to the Advanced slider?

Are you sure you have more than 3 reviews? If there are less than the number of reviews for one slide then it can't create the slider. However, the color of the stars should match. Looks like a bug for sure.
That is strange. You can use the same template on multiple pages. Can you provide the URLs?

Just an update. They are still working this issue. Sorry for the delay.
That should have worked. I just logged a ticket with scraping support. I'll let you know when it is fixed.
Seems to be a plugin conflict with Interlinks Manager. If you de-activate it then it starts working.

You would just go through and setup 2 different downloads. Go to the Get Reviews > Add New Source > Google. Then do it again for the other location.
When you create the review template you can choose to filter by source location or show all of the reviews together.
