I like how they are very transparent about their pricing, which is great for me as an entrepreneur who has limited resources to spend! They also have some nice tools in place when it comes time do integrate with 3rd party systems such as Magento or BigCommerce etc..
The support team at this point can be somewhat slow but if you're patient then things will work out well over all :) We've been working together since 2016 - so we know each other pretty good now. Our sites look exactly alike (same theme) yet our conversion rates vary significantly between them both online & mobile channels due mostly because of design differences/lack thereof- not necessarily anything related specifically ToAndZen's product itself :).
