This toy is a great addition to my prostate lineup.
I have an assortment of Fun Factory products and this was my first electric toy I've purchased, I am very happy with it. Eyeing up the Tiger g5 from Fun Factory next.
I'm a big fan of the waterproof &100% medical grade silicone these toys are made out of and the fact it comes in a few colour selections.
I also have the now discontinued Fun Factory Bloomy Prostate Massager, and it is great when I feel like a little analog version of what the Duke is. With the Duke I did not care for all the settings in the bullet vibe, the first one and the last two where the ones that stood out to me the most. The best feature of the bullet vibe is its easy of use and waterproof construction. Can take this into the tub or shower without fear of breaking it. I would say it is a medium strength vibration inside the Duke and high strength when used on its own. Perfect for someone entering anal play. It is a bit tight getting past the knuckle of the toy, just breath and take it slow its worth it. A good anal lube will be required for this.
The freebie lubes in the package worked great for this purpose I found the Sliquid Sassy was the best, it is designed for anal play and felt slippery and wet.
Over all a good vibrating prostate massager that's waterproof.
