Installation was quick and easy, got it up and running quite fast but got stuck with the modal part. I've sent an email to Artetics and I had the helpful answer within a minute or two. This is what I call excellent customer service. Thank you - you made my day.
Whoever is thinking of downloading this extension, I can only recommend it. I would also suggest to read the description to the end, because this is where you find out how to use it, otherwise you'll do like I did - "OK, I installed it. Now what?!"
