Rated 4 out of 5 by Expensive but ok. This is an expensive timer compared to some. But it is ideal as a direct replacement. Easy to use and no issues with it. 19 Sep 2015
Rated 4 out of 5 by simple fix Easy to fit and wiring in a doddle. Clear operation features for every age bracket. 16 Apr 2015
Rated 3 out of 5 by Does the job Basic controller to replace a 4 year old failure which was to replace a 10 year old failure. Once you know where the release catches are it is simple to replace the front panel that has all of the functionality to save re-wiring a back plate (which is left in situ). Seems a bit pricey for what it is and like many items, the usable life before failure seems to get shorter than the last one purchased every time you buy one. Hoping this one lasts longer than the unit it replaces. 12 Dec 2014
Rated 5 out of 5 by easy to fit programmer Changed for same as previous one had lasted for 20+ years and had finally stopped turning boiler on (a resistor had burnt out) easy to swap just had to take front control panel off, but as my rear bracket was cracked (where it is wired up to) I changed that as Well just swapped the wires like for like, no drilling extra holes even after all these years it is exactly the same. A bit more expensive than others on market but due to the reliability of previous one decided to stick with the same. 21 Aug 2014
