MPO 2500 - 8500 Compatible TENS Type Lead Wires 1/Pair = 2 Wires = 4 Pins (These are generic lead wires that fit the MPO device line).

I seen a couple of these similar items. I have to say my final decision to purchase this paticular one was because they advertise 4 FREE Electrodes and I said, "hey, I need those anyways, I'm getting this one" guess ? There are NO FREE ELECTRODES, if you read the item description, it doesn't say free electrodes anywhere. So don't be fooled by the pictures.

They're wires. They do as they're meant to.

Work fine

The convenience and the price was a happy fine. I am a recent user of the, Tens unit and was a little concern about ordering new leads and pads from the manufacture. Now when the need for the use of the unit will be less stressful because of the expense.Thank you,

These fit my old analog-type tens unit perfectly. I had bought another set elsewhere and the didn't have the old style pin to fit an analog port. Thanks! See the attached photos to make sure that your unit has the type of unit that requires these types of lead wires. They're great; I use them all of the time.

Great.

They slip out of the GEM STIM tens unit quite easily. Like if I sit down. If I put them on standing and walk they stay, but if I bend they can pull out.Also, the red stripe on the black stands out and I feel like a robot when it shows outside of my clothes. But it seems all the ones sold on Amazon have this red stripe.I am guessing they are all the same manufacturer/brand.

It does the job and the price is reasonable. That's why I ordered three. No problems with this product. Recommend.
