"The problem"
I bought mine and it is a useful safety device for the elderly; in our case going downstairs during the night when you do not want to use the main lights and wake up the rest of the household. The problem is the slider switch which is fiddly to operate. It is probably because to make the unit suitable for both in or out of doors the switch has waterproof packing. Sort that out and Presto? However, the nightlight which I have has the slider switch and that is also a problem. Signed BRIAN W.
