Rated 5 out of 5 by from Replacement This was bought to replace a broken fitting. The last one did 5 years in an office block WC so happy to replace like with like.

Rated 5 out of 5 by from An honest appraisal over time! About to go and buy my third - the second one has just become unreliable and jams with the light on. So why buy a third? - the last two have done nearly 9 years - and at this price in a commercial premises, that seems pretty good to me!

Rated 4 out of 5 by from Easy to Fit It was very simple to adjust the delay mechanism on the switch and the wiring and installation was very straightforward.

Rated 2 out of 5 by from Going to cause you problems I bought 4 of these to replace existing broken ones in a communal area in a block of flats. 2 worked fine. the other 2 the time didn't adjust, regardless of what you did to the screw on the back, so even when set for the max (about 20 mins) they turned the lights off after about 10 seconds. Local store staff were great as always in replacing these but it added a good hour onto my day and seeing a 50% fault rate has not exactly filled me with confidence and it wouldn't surprise me if they fail quickly. Only way I could recommend these is if you are desperate and can't buy anywhere else, then buy 2 for every one you need as you will probably need them!

Rated 4 out of 5 by from Columbus Pneumatic Time Delay Ideal for the garage. I bought this to replace an existing one that has been working for more than 10 years in the garage. It was used to switch on two 100W bulbs, when required in the garage, but must not accidentally stay on for long, in order to reduce cost.
