Great app to help our customers find the add-on products they're looking for. I really like that I can customise the add-ons for products individually, as this is something that really suits the products I sell. Support has been great- minor issue with my theme stopped SelUp working, but Dan had it fixed quickly giving me peace of mind.

Really great addition to the website. I'm not tech savvy but was able to easily get it set up. Due to my store themes the colors weren't very clear but Dan from support fixed that and also improved some other limiting things on my website!
