I honestly bought this as a joke because my partner and I are ravers so I figured I d surprise him one night by turning off all of the lights and just have this on and in and it was the best thing ever. I ve never used a metal butt plug before but I said fuck it just because I was so set on this joke for my partner. I ve gotta admit that something that was meant to be a joke might actually be one of my new favourite toys!! It totally converted me to liking metal plugs. Anyways, besides how great the plug is itself, the light up part is awesome. There s three different settings for the lighting, the button is a little hard to push when you ve got it in so be sure to turn it on to whatever setting you want it on beforehand! Overall I m pretty happy with this purchase, my partner and I had a ton of laughs and it will continue to be a funny joke
