The TPR material is translucent, odorless, and slightly sticky to the touch. While it doesn't attract lint as much as some other materials, fingerprints do seem to accumulate on the surface between washes, making the otherwise crystal-clear material somewhat cloudy.
The flame texture that runs along the length of the vibe is raised enough to add some slight sensation, but is not so extreme that it will bother anyone. I personally could only feel it while using it as an external vibe, and it felt great!
The bendable joint is magical. Looking at it and playing with it in my hands, there was no way I would have guessed that it would hold its shape during use as a g-spotter. But somehow, it just does. Perhaps it has something to do with the fact that the strong, concentrated vibrations don't require very hard thrusting to be effective.
As far as deep thrusting is concerned, the bigger bulges near the base of the toy would be satisfying for most users. The toy is long enough that I couldn't get it all the way in my vagina to test out the bottom bulge, though!
The controls are very simple: a single button at the base of the toy cycles through the four settings: off, low, medium, and high. While the low setting is a bit weak for me, there's no reason why someone who prefers light vibrations wouldn't like it. As I said earlier, the high setting is relatively strong for a vibrator of this size, and the vibrations are all nicely concentrated in the tip.
Unfortunately, this vibe happens to be loud. Once inserted, the sounds are dampened somewhat, but I would not recommend this toy to someone who does not have a whole lot of privacy.
While this toy claims to be waterproof, I did not submerge it fully in water. The battery compartment is sealed with an O-ring, which many companies claim makes toys waterproof, though water often leaks in anyway, making them useless.
This toy is made out of TPR, so it should be washed with mild soap and warm water after each use. It can't be sterilized, so do not share this toy with anyone else (unless it is covered with a condom), and do not use this toy anally (even a condom would not make it safe as it lacks a flared base).
Be careful that you store this toy away from others as toys of different materials can sometimes react poorly to one another.
The Bendable Flame can be used with your choice of water- or silicone-based lube.
Batteries should be removed between uses to prolong their life and that of the toy.
The Bendable Flame comes in a nice metal tin with a see-through plastic cover. It doesn't come with instructions or much useful information, but it makes for really nice toy storage. With the molded plastic insert removed, the tin has more than enough room for several toys or bottles of lube.
I personally don't get as much out of vibrations on my g-spot as others do, but I have had much success with the Bendable Flame on my clit while I use a non-vibrating insertable. The angle of the bent shaft of the Bendable Flame made this a lot less complicated than with some other external vibes.
