Rated 5 out of 5 by from Does the job unlike my eBay purchase. Bought some fish tail keys off eBay and although they worked on most switches, they could fail to turn back on some switches. This key is very slightly different and therefore perfect.

Rated 5 out of 5 by from Emergeny Light Keys - MK I bought these as they are a known make and were as cheap as the competition. Click and collect took a while as there was a que, but they do offer free hot beverages which is a nice touch.
