Physical Therapy 58769 Axelgaard ValuTrode Foam Electrodes, Performance and Longevity, 1.25" Round, Pack of 40

I use electrodes every day with a medical machine. The Valutrode electrodes are the most long-lasting of any that I've ever used. I was very happy with them. However, the second time I ordered I received a completely different brand. They did not adhere well and the leads did not fit well with my machine. I asked for a replacement and, again, received the inferior product so asked for and received a refund. If the Valutrode electrodes are no longer available, their picture should be removed from the sales page. Won’t purchase again after being sent the wrong product, an inferior one, twice.
