Extracts from a letter to Bio Electronics from Wendy Watson

"I am writing to thank you for the assistance you have given over the phone, and for the assistance your BioStim™ TENS has given to my badly osteo-arthritic knee."

"About two years ago I was told that a knee replacement was inevitable."

"Through a friend I was introduced to the pain management facility that is provided by your TENS appliance - and that was only three months ago. Since that time, the discomfort level has reduced sufficiently to allow me to cope with what housework and gardening is necessary for my peace of mind ... thereby making everyday life much less of a burden."

"I can now walk the hard footpaths while I am doing my weekly shopping without the onset of acute pain within a few minutes, which has been the usual pattern over the past year or more."

"I use the TENS appliance all day every day, which works, for me, much better than using it for more limited periods of time."
