Catholically review for Nembol: Sync & Edit instantly

I have been "testing" this software for almost 1 year -paying $49 a month- and the various different bugs encountered never allowed me to go live with sync among my different channels. Too bad; I really wanted this software to work. I kept on trying. Unfortunately, I just came to learn that Nembol doesn't work with different warehouse locations. I've learnt the hard way! Be careful: One can't connect a shop with 2 locations as products will be automatically duplicated from primary to secondary location randomly. Nembol will write (should I say overwrite) your current inventory even if you have all update switches set to off. Inventory updates can't be stopped. I guess I should have studied the documentation as suggested before connecting this app to my store. My inventory has been totally messed up by this. After damaging my store Nembol terminated my subscription without further notice (leaving the subscription active on Shopify ready for the next bill). Maybe a tool for basic stores with few items 1 location. Not my case.
