I enjoy using Modor for creating book mockups. It's great that they have a bunch of free templates and I love that they are easy to use. The free PSD mockup section is fantastic, and all their mockups look premium. I like downloading the free PSD mockup templates and editing them in Photoshop, which gives me more flexibility to make my mockups more realistic without any extra cost. Setting it up was a breeze too, as you just need to click on Gmail signup to log in. Overall, I rate Modor a 10 and would highly recommend it to friends or colleagues.

I haven't found anything specific that doesn't work well but yes if you are creating bulk mockups and add 50-60 mockups to one project it can slow down a little. Review collected by and hosted on G2.com.
