"I have bought/tried extensions from almost every major developer of the entire Magento Connect site. I have requested custom services from most of them too.
This extensions is without doubt one of the best extensions I've bought. It's very well written with no core modifications.
The service is one of a kind. I requested a custom feature and Lucas implemented it less than 1 day! had a small issue with a 3rd party extension an it and was fixed within hours.
I highly recommend this extension to anyone looking to automate the boring and time consuming process of manually assign products to categories."
