Where to start with the double dipper, is the very question you may ask yourself when you're about to use it.
Doggy? Cowgirl? Missionary? etc. All good options depending on your anatomy.

I have tried the double dipper I various positions and found that you really can't go wrong as long as have it in the correct position, But hard to recover from if wrong (more on that below)

The dipper is silicone and while not the smoothest and most luxurious I felt it is still smooth enough to provide an easy entry with lube(I use aloe lube. It is thin enough with a 2' diameter even with the bumps for the novice and depending on the girth of the partner of the toy it's attached to, you can be felt rather easily from both sides.

With a 6" length, it has some room to start with a bead or two before going all in and won't feel overwhelm at all.

The bullet as well as the toy itself is waterproof which is nice, and makes for easy cleaning with our fear of ruining the bullet. The bullet comes with 10 settings all controlled with a single push and had a 3 flutter fins for clitoral stimulation. The setting are nice, but all mild to strong without a lower setting.

The Ring is stretch and comfortable on the shaft of the penis (I just wanted to say penis)

I have put myself through various positions to test this toy (For Science!)
And found that it works well no matter the positions, but believe depending on body type the toy may not work everywhere. I'm a petite gal with a butt and had no issues with pose and that is great.

The draw back to this toy is if it is improperly positioned on the toy or penis involved. If you look at the dipper, the insertion part had a flat back and if that isn't pressed up against something, the toy sort of wobbles and can ruin the flow. Causing the toy to feel odd at play.

So when switch position that involve turning the toy around (missionary to Doggy) it is important the part get things set up correctly and make sure the back has something to push up against or support it.

Depending on the sensitivity of the man's balls, this may take getting use to for toy under shaft postilions.
Of course with a toy it's just about alignment.

Dipper is too thin (for most) to be used vaginally with a larger toy or penis for anal, but he bumps are nice if you can get the right. But why put in that effort, just use a vaginal toy

My last gripe is that the bullet doesn't have a low setting... I prefer to warm up to stronger settings rather jumping in to any higher ones.

Still a fan of this little guy, makes for a nice warm up or a addition to variety in feel. plus the partner likes the waves as the bump can be felt for him on the other side.

It's all about the placement of the toy, be patient and get it right the first time
