I read a lot of reviews and worried a little when I decided to use them to build my photobook - but I wanted access to all the "shared" materials for my Disney book. The tool to build the books is online now and I found it easy to use. You could select to hide pictures you've already used or it automatically put a checkmark on pictures you'd used. It let me know when my pictures were too low resolution and it was easy to upload a large number of photos.
The book shipped within days of ordering - NYE was during the wait period. The book was delivered within 3 days and was well packaged.
I have no complaints about the quality of the product. I had some pictures that were grainy and fuzzy - which was my fault for using a phone instead of a camera. I would order from them again - and the buy one get one free was a good deal.
