I purchased the plugin for its low cost. For a single license, it costs less than what others charge for a month. For the price/value, it earns a 5 stars.

When I purchased, it did not work out of the box, there was a bug preventing some rule being displayed. The Quality earns a 3 stars.

When I reached out to support, they were able to fix the bug quickly. 5 stars for support.

The documentation earns 2 star for barely have any documentation, the only doc in the plugin just mentions there's a global and per product setting. There's a lot of room for improvement, ie.make a youtube video to teach users how to use/config. Alot of plugins do this, and also as a way to sell/advertising their stuff. So, get out there and sell you plugin. This will also cuts down your support request.

Overall, all things considered, I'd rate the plugin as 4 out of 5 stars. Good job!
