I haven't opened my store yet so this is a review on the install and customer support rather than anything sales related. The app was easy to add and straightforward to use, I requested a few minor amendments and my support ticket was answered quickly and professionally - Thank you Dan. Very happy so far and it does what i wanted it to do.

We have yet to really utilise the app because we had a little coding issue but Dan was able to sort it super quick and was a pleasure to work with! Looking forward to seeing some results!

This app is great, it has led to quite a few upsells which is great. I had trouble installing one of the features on my site so I reached out to their support and it was fixed almost straight away.

I installed this app on our account and it works exactly how we thought it would. Dan, was great with support. He got the app working on our purchased theme from Theme-Forest. I would recommend this app to anyone needing more out of their Add-Ons.
