Review on TensXtends Conductive Adhesive Gel For Tens Pads - Patented Formula To Extend Electrode Pad Life Of Your TENS And EMS Units (2 FL OZ) by Christopher Morgan

I don't necessarily agree with the claim of three dots equals 3 weeks of adhesiveness/longevity in your electrode. I think it depends on how many times you move it around and restick it, versus the length of time the stickiness. I move my electrodes from different areas to different areas and I would say I get at least 5 more good sticks out of them before I feel I need to reapply it. Definitely have some extra electrodes as you need to wait overnight before using it again after applying the gel. This will definitely save you money on buying new electrodes.
