Any experience with the Telin TL20 thermostatic radiator valve ? + Radiator valves discussion

This summer I’m looking to replace all my radiator valves with smart ones, as way of reducing energy consumption (rooms that need heating change a lot) by controlling the heating at a finer level.
I’m thinking of buying this model (Z-Wave variant) and I’d love to know if anyone had experience with it or the brand.

Discussion and insights about smart radiator valves are also very much welcomed.

Thanks !
