Great for patients that are bed-ridden. Once stick it to one place, you'd better not remove it frequently. Otherwise, the stickiness of nylon fastening tapes may be reduced more quickly. Before sticking it, clear up the dust, making it more sticky onto the surface. If you don’t need it for a long time, please take out the batteries and keep them well.
