The Duo was a toy my partner and I were extremely excited to try. It is actually our first strapless strap-on, and since then we have tried a few. However, it is a classic and deserves recognition. It has its flaws; it's a little too short and too smooth so it can slip and slide right out of you and make it challenging to get right. BUT it is also great for couples looking to try mutual stimulation in their pegging adventures. The bullet that comes with it is powerful and travels throughout the toy, and the heft to it feels nice when inside. You'll have to get creative with positions if you plan to use it for anal, we found the shaft was too short for us, but for people who are not looking for a lot or looking for a good beginner toy, I recommend this one. The size is friendly and not intimidating to use.

This toy is smooth like an eel. Well, it's actually velvety. If you have silicone toys, you know that super soft touch they have to them. The problem is that it becomes hard to "hold it in place" for the top because it can be so slippery without any bumps or grooves to keep it from sliding back out. It's still amazingly soft, and while it is firm, there is a slight give that makes it feel good. The smaller size is beginner friendly, but for experienced users, I suggest looking for something with more texture to have a better "grip" on it.

So besides the color is one of my favorite parts of this toy, the thing I really like is how the grooves are positioned towards the base. However, because the toy is very smooth, it has a bad record of slipping out easily with an abundance of lube or slick. With that, my partner and I used a jockstrap to help her keep it inside her. That defeats the purpose of the strapless strap-on, but considering we wanted a toy that would give us both stimulation, adding a thin strap to keep it secure was worth it compared to a bulky harness. As a suggestion for improvement, I would like to see the bulb that enters the top to be bigger. All in all, it was our first of this kind, and we did eventually upgrade, but we still liked the uniqueness and affordability of this toy.

One of the saddest parts of this toy was that the shaft fell short for anal, but we made it work by getting very close to each other. Regardless once we worked out the kinks of it falling out of her, we did like our time with the toy, after all the bullet it comes with is pretty impressive. It is meant to be used without a harness of any kind, but for extra security, I suggest finding a packer (FTM) jockstrap to add an extra level of security. If you have a lot of control of your vaginal muscles, I'm sure you wouldn't have as much hassle as my partner did. We did like that it basically "had a handle" for solo play, or to use on your partner if you don't have the physical stamina to hold it.

If you are looking into "double ending" dildos, a style like this is worth giving a try with any water-based lubes. The price is more than fair, and the toy is completely silicone, meaning it is one of the most body safe materials. I store it in a plastic ziplock baggy by itself after rinsing it off with hot water. But if you want to clean it deep, take the bullet out and wash it more thoroughly by boiling or using the dishwasher. Cloth bags can be useful for storage too, but I find they leave lint on silicone toys and I prefer the convenience of wrapping a condom on the toy and going without needing to rinse off any dust. I also recommend you take the bullet out or remove the batteries, as the button is easily "bumpable" and you don't want the bullet to turn on when it's in storage!

The problems my partner and I ran into with the slipperiness and the shaft being a bit too short is likely anatomical problems. Her genitals are "further back" than maybe the average girl, so we took into consideration our bodies and overcompensated to make the toy work for us. Most likely if you have a more "up front" opening, you'll find the size more than enough. I'm just a little size king and like more, but it's since become a really fun "warm up" dildo for us.
