A proper shower when teamed with thermostatic controls.
A good powerful shower rather than the previous gravity fed dribble - very refreshing.
Well thought out and complete kit. Easily installed by a capable DIYer - (caveat: have electrics properly checked!)
Make sure you have adequate hot and cold water supply - it must not run dry!
It does hum a bit and needs isolating base (hence 4 stars). That said, it will depend in siting position.
