Lots of units showing up on Amazon and ebay,,,at VERY reasonable prices WITH attachments. I recently took a flyer and purchased 2 (different accessories) and was really quite pleased with the products AND the results!!! Both were under $20 and shipped from the US (California)…both arrived in less than a week. AND both worked!
The first one had a “glans cap” that I used with an anal plug for some interesting results. The “cap” was a little snug (I'm average probably) but if you “stuffed” yourself in while flacid things eventually worked…and a very erotic feeling.
The second one came with a butt plug, 2 cock rings/bands, and a urethral sound. The plug is about 3 ½ inches long with 3 balls stacked on to of each other; The first or topmost (the one that goes up your butt first) is about ½ inch, the second about ¾ inch and the last about an inch…followed by a flat plate to keep it from slipping in. It is chrome plated (I guess) and solid heavy metal (the whole thing MAY be stainless steel…I'm not sure). The urethral sound is roughly 5 inches long, with rippled beads, and is maybe 3/8 inch in diameter.
Used one last night with the anal plug and the urethral sound. FANTASTIC!!!! (The power unit, by the way is pretty cheap plastic and powered by 2 AAA batterys…3 volts total. At full strength it was adequate but a little more “oomph” would have been nicer.)
Anyhow, there are a bunch of these things out there at basically the same price point and for my money, well worth a try.
Just a note (and if you've played with e-stim before you surely know this) USE LOTS OF LUBE!!!!! (I use KY , but there are lots of others out there…Astrolube pops up a lot.)
Go get 'em…and ENJOY!!!!!
