The evolution BJ is the little sibling of the Evolution XL. A more compact yet still powerful and fun experience. This toy is one of the finest in the auto stimulation category. This is a toy that is geared around solo play, but could easily be used with a partner. This hand held device can work like a stroker manually, or you can just hold it onto the penis and let the toy's mechanical parts do the trick. This toy is fairly discrete, but you will want it hidden. It is compact enough, as it is smaller than the bulkier toys such as Fleshlights. Unfortunately there is no deception to its design, if someone lays eyes on it, they will know exactly what it is.

The inner sleeve of Evolution BJ is made of high-end silicone. Silicone is a flexible, heat-resistant, non-porous, nonstick, rubber-like material that requires very little maintenance. Silicone is a polymer that contains silicone with carbon, hydrogen, oxygen, and sometimes other chemical elements. One benefit of silicone is that it lasts a very long time. It is important to note that this toy is also hypo-allergenic, latex-free, and phthalates-free. The internal texture of the sleeve has many small bumps and one large groove on each side, along with a tongue like detail that adds to the mouth like look.

The smooth outer shell is made from hard plastic, and has a lot of sharp angles. The angles do not add much to help grip the toy but looks very nice. The plastic feels thick, and very sturdy,.

This toy out of the box had absolutely no odor and no paints that will rub off on the user.

This toy, while smaller than the original Evolution, it still has some heft to it. This toy should be pretty easy to hide, but you may want to wrap it in a silk cloth or place in a small bag because the design is not deceptive at all.

The size of the user should matter very little when using this toy. This toy should be able to fit the smaller to the larger of appendages. the material of the sleeve does have little bit of stretch to it. The sensations this produces isn't exactly the same as a "BJ" but if you use your imagination it does fairly well. While it might not be a perfect simulation of that sex act it is absolutely a great experience.

The Evolution BJ has three main functions, vibration, rotation, and heating. In addition to these main functions, this toy also has three power settings (High, medium, and low). In addition to the three main power settings, there are 7 additional settings or patterns to the rotation as well as 7 additional for the vibration. This allows the user to fully customize their experience.

Thankfully this toy is very quiet even on the highest setting, which is very nice, you shouldn't have to worry about someone outside the room you are using this hearing the toy. While it is quiet, it still is quite powerful, so there is no sacrifice of power for noise control.

While there is a little information given with this toy on the packaging, it will still require a bit of exploration. That being said, the toy is very easy to learn. You can also find the users manual on the product page, which gives straight forward instructions on how to use this toy, however there only a simple rundown on the back of the box. The icons are pretty straight forward, except the heating option. To turn on the heating option you click on the furthest button near the bottom until it is blinking. The power button is also your speed selection, and has three settings. The heat is very nice, and there is no worry of burning any part of the body. When you click the other icons you can cycle through the patterns of vibration or rotation.

Since this is made from food grade silicone and non porous, the inner sleeve should be able to be fully sanitized. However I would caution putting this in the dish washer, and certainly would caution against boiling this toy. The hard plastic shell could be damaged, and the intricate mechanical parts could also be hurt in this process. That being said, warm water and good anti-bacterial soap should do fine with cleaning this toy. You can use a small towel to dry the interior if you are careful, but I suggest laying it out to air dry. Make sure the toy is completely dry before storing away.

The packaging of this toy was simple, yet eye pleasing if it was in a retail setting. The box had limited instructions on it, and it did have a pretty good run down of the features included. The packaging was classy enough that could be given as a gift. After opening the box though there is no real reason to keep the packaging. You can find the user manual on the product page (which has more in-depth instructions), which will allow you discard the box.

I love this toy. It is my favorite toy in my ever growing collection. I think i have about 20 Flesh lights in my collection over the years, and I think I am getting close to 50 toy reviews. I loved the Evolution XL, but I broke it. After exactly 14 uses (Yes, weirdly I counted). The original Evolution XL's "Failure" was entirely my fault (Broke the silicone from the plastic, and the internal mechanics broke down at the same time). I abused the hell out of it and went back for more. The down falls that the Evolution XL had are not present here. I feel like I could get a lot more uses out of this than the Evolution XL. The only thing I think may break down with this is battery life finally ending, but I think I should get a year or more out of it with moderate to heavy usage. Speaking of battery life, just like the Evolution XL, this has pretty good battery life that allows for multiple uses per charge, expect I believe this has even better battery life.

Perhaps It is me getting lazier in my older age (early thirties!), but I genuinely love this toy. Auto toys are always hit and miss. With most toys you have to hold it just right and it never seems to be strong enough. This toy though is easy to maneuver and can use it in just about any position, and the high setting is powerful enough to get the experienced user across the finish line. The only issue I have is turning it off quickly after... crossing the finish line, cause it can be a little uncomfortable right after the race when everything is sensitive and this thing is going full pace.
