From April 14th, 2017 to April 1st, 2018, 100% user give 2-star rating. for PinCo Collage Maker for Websites PRO chrome extension.
Stopped working back in 2017 and not a peep from the developers. Its a shame since it was a great tool otherwise. However a Pinterest collage maker that doesn't work with Pinterest is a bit of a fail.
Randomly pulls images that are not in my board, very difficult to handle the zoom in/out function or eliminate some images, and suddenly entirely stopped working out of the blue. Bummer for a paid product.
