Making its debut is this affordable vibrating penis/dildo casting kit that is bound to get rave reviews! Easy to use, this kit has everything you’ll need to cast your favorite “member” in non-porous, safe silicone, with the added pleasure of vibration (a 4” vibe is included).

This fun, erotic arts project can be a great bonding experience for a couple or two friends (the timing of creating the mold requires at least two people), with the finished product being an extremely life-like, life-sized vibrating dildo. Bravo!

Rating exceeded expectations December 8, 2010

Reviewer: Customer Review

this exceeded expectations -- it looks completely like my lover's dick and as such, we are quite fond of it. we added a tiny pot of fine glitter which really helps, otherwise the colors are kind of muddy. follow the instructions exactly!

Rating Best Vibrator Ever! December 8, 2010

Reviewer: Customer Review

I thought this would be a great activity to do with my husband and not only was making it a lot of fun (and educational), but it is actually a top notch vibrator ... to the point that I don't use my others anymore. The only drawback is that bubbles in mold can make the surface a bit rough for internal use but it's excellent for external play.

Rating Not ready in minutes! April 3, 2010

Reviewer: sexay

The packaging claims it only takes minutes. Ok yes the actual stirring is minutes, but then you have to wait 2 hours to add the latexy stuff. Then you have to wait another 24 hours to pull it out of the mold. So it's not a quickie by any means.
The store clerk warned me to read the directions a few times, definitely necessary. But with the directions claiming you need to not take longer than 30 seconds to insert penis into mold stuff, it makes it very difficult to do it properly. Also, as the other reviewer said be very careful when inserting the vibrator.
And yes I ended up with patches where the latex didn't make it around the vibrator.
The only part of this that resembles my partner is the head.
$45 was way too much for this experiment, I'm going to order another brand off Amazon for half the price and see how that works out.

Rating Some skill required November 3, 2009

Reviewer: CWM

I was very excited to receive this as a gift. I read the directions many times, but I rushed through the process and wasn't totally happy with the end result. Make sure to use a big bowl and stir the powder mixture thoroughly. Two minutes is longer than you think! Then when you are inserting the vibrator into the rubber, take some time to place it well. I didn't pay attention to the curve of the mold, so one edge of the vibrator is coming though the rubber. Since I didn't stir the powder as well as I should have, the finished product has white powder flecks and lumps. The rubber is rougher and stickier than I expected, which makes me wonder if I didn't stir the rubber together properly either. I think I would be much happier with the product if I had taken more time to stir.

Rating Martha Would Be Proud October 20, 2009

Reviewer: Nadia Boots

The Understudy is an erotic art project that is a perfectly unique gift for the kinky Martha Stewart in your life…. much more than just a toy to play with; it will probably be the most naughty craft project you'll ever partake in.

Rating Two Heads Are Better Than One October 20, 2009

Reviewer: Mr K

"How do YOU like it?!" Ms. K asked.
It was actually nice in my own ass once I used enough lube. Oh, and obviously that firm material lends itself to transmitting the vibrations rather nicely.

I was staring at an almost exact replica of my favorite cock. I couldn’t help but be impressed by the detail and lifelike shape of my new toy.

Rating And then there were two... September 16, 2009

Reviewer: SexyRexy30

My hubby and I love the fact that there are two of him now...I created a base area for the toy by running my fingers along the top of the mold after the goop set....its a anal toy (cause of the base..use condoms though) so we can do d.p. with just he and I...and its a vajayjay toy when he is tired or times I want to make a hand so it can be a g spot times

Rating Wonderful fun December 21, 2008

Reviewer: Amythyst

I highly recommend this product! One day I went looking for a dildo to use when my boyfriend is away, (at the moment we have jobs 1500 miles away from each other,)and found the Understudy! I bought it, and the next time we were together we made a dildo for me that is the exact replica of his penis. It was so much fun to do and quite easy too! The thing that is so interesting is that having a dildo of him really does make a difference. It is so wonderful to feel his exact shape and size in me as I fantasize about the next time we are together.
