Tenga's Flip Hole Red is a great toy for individual use or for couples use. If you are not familiar with the flip hole family, here's the general idea:
The flip comes in four styles, the red being a more gentle interior texture. Each flip comes with three lubricants with varying degrees of slip and density. The flip can be opened by sliding the "pronged" base off. You can open it to apply lubricant before use and to wash it after use. After washing your flip, the pronged base can be use as a stand to let your flip air dry safely. When dry, you then secure your flip back onto its base for easy storage.

The flip is really great for those who are looking for a masturbator, but don't want a huge "flashlight" looking device. Its use is basically endless, whether it be for travel, in bed, in the shower, ect.

I am beside myself over how awesome the feel of the flip is. Tenga has perfected the texture in the flip, giving realistic feel, yet out-of-this-world stimulation. The red flip in particular would be great for newcomers to the masturbatory aid world, because of the gentler design on the interior.

When it's not in use and being stored, I love the design because you really have no idea what it is. By no means when someone passes by this are they going to think "J/O TOY", because it is discreet and sleek. The three buttons on the outside of the toy control the suction and pressure that is delivered during use, and can be customized to each user's preference. For some, using this may be a two-hand job to stroke and use the buttons simultaneously, but most gents will be able to have one hand free. It is slightly bulky... so if traveling, I'd suggest putting it in a checked-in bag, not a carry-on.

With the three buttons on the side, the individual control and performance you achieve with this toy is unparalleled. No flashlight toy is going to give you the customization you will get from a Flip.
I will say that this toy is best used if you are in an area where others can't hear you if you are trying to be discreet. The suction on this toy, partnered with the lubricant, can make for some loud noises.

The flip's design makes cleaning and storing a breeze! After use, wash with soap and water and hang over the pronged base to air dry. When dry, return the toy to its base with the insertion end first. Tenga offers three different kinds of lubricants with the flip, and to be honest, I like them enough to where I haven't used another brand with it. From my experience with the toys, I believe you'll want to use a water-based lubricant, but don't quote me on that.

We've used all four varieties of the flip, and I must say that the red version is our favorite. The more gentle textured interior makes for longer, more exciting play time. I love all four flip holes, but it is nice to be able to have the stamina while using the red flip.
