I purchased this about a month ago, for a project that needed the QR codes to be trackable so at this price for my project it was worth it.

The qr codes can be static or dynamic, the function for customized qr codes with logo it's not great. you get a tiny logo in the center that is bearly visible. But it's nice that you can track them, how many times it was used, device type, location etc. Usefull information when you lunch a campaign to see how it's going on printed objects at least.

Then you have the other features that are really useful, like personalized link, custom link, you can add the pixel to the links to measure how well it performed and other cool stuff. I haven't used all the tools there, but are a few of them that can help you manage your campaigns better with better results.
