Simple to use and Easy to fit
This was bought as a replacement for a similar switch that had failed. It is used to manage immersion heater consumption and is very effective. The only issue is that the relay component of the switch has a tendency to â chatterâ and then fail over time, (3-4 years) but having said that theyâre relatively inexpensive and easy to replace.

Money saver
Simple to fit and easy to use. Was a bit stumped by the fact that thereâs no earth terminal, but then noticed the chocolate block in the box to connect the two earth wires together.

Easy to install
I had read the others reviews about ease of installation etc and took them with a pinch of salt. However it was very easy- installation took a few minutes (I noted which cable went where on the existing broken one before I swapped). Our fault was the one described as “chattering”

Does the job well, easy to install (hard wire)
Theyâre not digital which is good. The blue LED is quite bright at nightâ¦

Easy to everything
Easy to fit and use, best timer for the immersion. No more leaving it on all day. This should pay for itself in saved electricity very quickly.
