m.a.b.e.l. review for Inventora

I have been using inventora for 18 months (or so). I want to love it. The interface works with my brain; it's clean and it makes sense to me. BUT it's laggy (both the website and support). There's no clear-cut way to sync between Inventora and Shopify without TONS of duplicating work, and the lagginess means this. takes. forever. For example, I'm still waiting (30 minutes later) for the products I created on Shopify to sync with Inventora. When I reach out for support (please, please please just tell me the correct way to do this), it's days before I get a response.
