Wet-Gel Electrodes (Pack of 10)

I prefer to use the gel pads because the clips are quite strong and can crush or mark the leaves. I often wonder if this stresses the plant. But the gel pads are gentle and produce great results. The only drawback for me is the cost of postage, as I live in UK it means the amount I pay for them is more than doubled (£19 postage). But I really enjoy using the pads.
