am a tier 1 user, doing simple apps as per my needs.
Nowa came and made it easy.
yes it has some issues, but the team do work hard to upgrade/update and add many features to try to make it better by time.

The only downside is the team is almost at full capacity and sometimes they take longer time to respond (but it is not a huge issue since the respond).

i hope they can make more documentation and tutorials on how to use each item so we wouldn't send much requests

am thinking to upgrade to tear 3
