I am sending in the APK controller for maintenance after having been used steadily for 3 ½ years. I have been told the pumps last about 3 years and if true it has done well.
I have had 2 terribly deep pressure sores since 2009 and your cushion has made it possible to sit up and the sores slowly healing. One was as large as a grapefruit to begin.
I wish to thank you for all of the help that you have given me over the years. Your products are the best and I wouldn’t be up and about without them.
Thank you so much!
