Dy4848Wsl Elite Silver White Cloth Silver Electrode, 2" X 2" Square,Bio Protech Usa, Inc. - Pack(Age) 4

Conductive gel pad and top layer began to peel after a month. Shortly there after one of the wires came loose. Given that the complementary electrode pads that came with my unit lasted over 2 years I find Bio Protech's quality to be under par.
