Testimonials

"

The treatment centre was having a large number of instances where a patient or visitor was pressing the emergency call bell when attempting to locate the light switch in the visitor’s toilets. This was causing the emergency team to be alerted and go into action unnecessarily.

This would occur once or twice a week.

Since we have installed the Stopper II covers, the instances have stopped.

We have had one person who has lifted the cover and pressed the button, (why we do not know) but, it proved that the emergency buttons can be reached and activated easily if required.
