Elkay Columbus Pneumatic Time Delay Switch is rated 2.7 out of 5 by 12.
Rated 2 out of 5 by from Did not last long - avoid I bought it despite other negative reviews. It would have been a great device had the reliability been better. Unfortunately, the switch survived only one month of relatively light use. For the money paid, I find the value very poor.

Rated 5 out of 5 by from Tough and easy to install Solidly made and clearly designed for quick and easy installation.

Rated 5 out of 5 by from Good flexibility Bought this as I'd hoped for the longest delay to switch off again Packaging says 5 mins, I timed this one to 7:48 which is excellent. Only time will tell if it stays as long as this but so far so good.

Rated 2 out of 5 by from Sticking timeswitch I have used these many times being an electrician but this being the 3rd one now i'm not sure if I will use again, the unit works well for a few weeks then it seems to stick and stay on. Elkay say they have improved on this but it remains to be seen. if your able to use the electronic version do so,it may be more reliable.

Rated 3 out of 5 by from Good basic switch For the price this does what it's supposed to. Setting up takes a little time but is not difficult. The first one of these I had sometimes wouldn't switch off but it was replaced without any problems and the new one has worked OK.

Rated 2 out of 5 by from Not very substantial. Two switches were fixed in the staircase of a student let as they left the light permanently on. One failed within a year and would not switch off even though the plunger was fully out but if the casing was touched it would then switch off. So far so good with the replacement. Motion sensors fitted on the other floors have been great. A new section should be added to University Challenge with questions such as how do you turn the heating down and what day do the bin men come?!

Rated 4 out of 5 by from Does the job I bought this switch to control a sink macerator. Hidden behind the kitchen curtain it looks brilliant. It is set to 15 seconds and works great! I don't know about reliability yet but if I get a couple of years with that load I will be happy.
