The curtain motors are very nice, easy to setup, good integration with homekit via matter, good automations in the switchbot app - pretty much set it and forget it.
The hub 2 to control an aircon via IR is a bit hit and miss, not sure if it's due to matter or homekit or both, waiting for an upcoming update before buying more.
No regret to buy at all.

Twice as strong as Curtain 2 and much quieter.
The solar panel helps keep the battery charged on sunny days. Very easy to connect to the app and automate.
