Rated 4 out of 5 by from Not perfect but....... Bought this to replace a different brand of timer switch controlling our bathroom towel rail. No problems wiring this in and once you work out the indicator light workings you're fine. As our one is mounted low near the skirting board, it's not easy to see the glow from the light. The first time I set the unit to not come on as we were off on holiday for 2 weeks, we came back to a very warm bathroom. I'd lowered the flap down, slid the switch over from 'auto' to 'manual' while the timer was off and then closed the flap not checking the light. What had happened was as I closed the flap I had turned the timer on and, as I had switched it to manual mode, it stayed on for the 2 weeks we were away. The indicator light would have been showing a flickering glow but as it's mounted low down, I didn't notice it. A lesson learnt! Otherwise it's all working fine.

Rated 4 out of 5 by from 7 day electric timer. Not a bad timer but doesn't work correctly with led bulbs, when the timer is off the led bulb will glow slightly. There is a small current that is allowed to flow to recharged the battery this is what manifests itself at the led bulb hence the slight glow. A regular tungsten halogen bulb is fine because the very low voltage to charge the battery isn't enough to power the bulb. If using a low energy bulb then in the spec sheet it states it has to be no less than 17w.

Rated 5 out of 5 by from Perfect replacement Replacement for one that lasted 20 years so hope this one does too! Great to be able to time random but chosen switching for outside light. Not sure why this has a fuse option - it works without. Best price and good service at Toolstation

Rated 4 out of 5 by from Plastic is flimsy Easy to install. No issue with the set up. Plastic casing is not good quality
