First off, I had to wash this Yocare Thrusting Vibrator with Remote Control very well, and several times, before using it, as it reeks of strong chemicals straight out of the package. I actually put it into a UV sterilizer after washing it, just to be on the safe-r side.
Because all of the instructions are written in Chinese, you kind of have to figure things out on your own, unless you can read the language. I thought mine was broken, until I tried the remote. The remote is what controls the fun aspects of this device. So, if it breaks, you lose it, or the battery runs out, you're screwed. Well, not anymore!
The thrusting functions are all controlled by the remote, which really frustrates me, and not in a good way. Though I like having a remote, it should not be what controls the most important functions. Without the remote, all it has are vibration patterns. I took off two stars for the above mentioned issues.
Other than the smell, Chinese only instructions, and all important functions being controlled by the remote, this is a pretty fun device. It definitely gets the job done, and quickly. I just wish the above mentioned things had been more thoughtfully cared about in designing this device.
