Review: Absolutely awesome little attachment. - This is about the most perfect little attachment for the iStim device. It is long enough to be easily felt while inside, stimulates the muscles exactly as it is supposed to and if one so desires, it really makes one feel explicitly nice. I cannot recommend this attachment enough. The one that comes bundles with the original kit is simply too small for what I use it for while this one is perfect and reaches that oh so small gland which only men have and stimulates it equally as well as contracting and relaxing the muscles needed as one ages. You cannot go wrong with this attachment.
Review: Oh, yeah, this does the trick - Used this probe with my TENS unit. It was the first time I used the TENS and wound up inadvertently turning it up to full volume, which just about launched me into space. I came to find out it doesn't require much voltage to do the trick and offers a very pleasant sensation at more moderate levels. Happy with the purchase and I can recommend it to anyone looking for either anal or vaginal electrostimulation. Or more.

## Questions & Answers

**Q: Is this compatible with a belifu tens sm9126?**
A: Doubtful, tried to get it to work with a Tens 3000 and a tens/ems Belifu, but neither would work. Both units work fine for my back and muscle aches. In my opinion, this thing is a POS and the company didn't even reply to my complaint. Also can't be returned even if not actually used. Can't even get a replacement!

**Q: Will this work with a istim 820 machine?**
A: Yes

**Q: Would it be safe to use a condom over the probe for easy clean?**
A: A latex condom is not electrically conductive, so it would prevent the probe from functioning.

### ⭐ Doesn’t work
*by M***Y on March 3, 2023*

Do not buy this product. It does not work. I connected it to my Zynex that has an NMES setting and just held it in my had. There was maybe a tiny tingle. I tried it on the ten’s setting as well with dismal results. It looks pretty. It is quite small so the comments on the girth and length issue are laughable. Save your money, try the Intensity or Apex if they ever start making them again as they work great on pelvic floor.
