I've been using Woobe for over 6 months now and find it's such an excellent and easy way to manipulate woocommerce items. It looks a little complicated at first but once you actually take a look it's very simple.
You can easily edit one item or 1000's of items with simplicity. You can also change the fields that show up so if your are editing some field in particular you can just show that field and it makes it very fast for editing.
What used to take me days and days now just takes a few minutes.
Incase you make a mistake it has a history that allows for a fast undo.
The one little issue is you can only have 100 items per page, while most shops that probably isn't an issue and I realise its also an issue about page load times as well. Just sometimes 200 or 500 items would be nice for me.
It has helped me migrate from prestashop to woocommerce and still have products look nice.
If you run woocommerce and have a large shop, I can't recommend woobe any higher, take the few minutes to learn it and it will save you 100's if not 1000's of hours of your time.
