Clear instructions and robust construction. I used this to replace an existing one that had been in operation over a quarter of a century, the layout and box size exactly the same so I didn't have to faff about replacing the back plate. Full marks Horstmann!

This boost timer is brilliant for the immersion heater which is only ever used in emergencies in our house as we have a gas boiler. Before then there was just a switch we would put it on for whatever reason and then usually forget and find it still on 24hrs later.... hence the argument "who left the immersion on". It is so easy to reach in the cupboard and select 15/30/60mins on the button to get just the heat period you need... then you really can forget about it.

The unit is easy to fit despite being slightly more bulky that other controllers. The unit is very easy to use and has a quality feel about it. Overall it is a very good product.
