Absolute rubbish. You will constantly switch leads due to the low impedance, e.g. B. "V1, V2, LA lead". Tons of lead waste, tons of wasted time. Turns a half-minute EKG into a half-hour disaster. I thought my Midmark EKG machine was bad. The glue is so lame that the weight of the wires pulls them together, the conductivity is worthless. So much time wasted with this junk. I have a different brand, no rework, no lead dropouts, great shots. The McKesson ECG Tab electrodes (also Amazon) are fantastic by the way. If possible negative star rating!
