Metafields Guru

We have a large catalog with 20000+ products and we use Metafields Guru on almost a daily basis and it is a real-time-saver. I have needed help on a few occasions and the Support is first-class! Always fast and they go on and beyond helping us achieve our tasks. Recently, they helped me generate an impressive number of metafields (19772 to be exact) based on some random keywords in our product titles/descriptions. Very impressive. I would leave 6 stars if I could.
