I liked how powerful the app is when it comes to personalization, however the BIGGEST problem it came bundled with was SPEED. My store's speed drastically decreased the moment I added this app which was definitely a no-go, no exceptions. Hence the 1 star. I do not expect a response on my review because I had deleted the app only after trying quite a few ways to get the speed issue resolved without compromising the app itself but the scripts they use are the real culprits. The support was swift, but my last email about what files/code to remove in the product template was never responded.
