Useful - but poorly implemented
Experience has shown that it's sometimes a bit "Hit-or-Miss" whether the first touch will bring it On or Off: keeping a finger on the 'On/Off switch end' does allow the 'tube' to dim down, but this biggest problem identified in this household is that the tube 'flickers' when it's On - very disturbing to one occupant here! The colour temperature isn't very good, being too much on the Warm White side for a bathroom.
