Triton 83308460 Thermostatic Cartridge by Triton Showers

Arrived quickly, not in the best of packaging but was undamaged.It was fitted a few days later and works as it should.Note: No fitting or set up instructions were included with the item.The fitting is a straightforward replacement of removing the old unit and screwing the new one in. Take care not to damage the spline by using too much force with the spanner when tightening it.Setting the temperature does need a little care but also straightforward if you follow the instructions, which luckily I had in the original manual that came with the shower.
