I can agree with most of the other comments. This rotor is pretty good and continues to work well after several uses. The rotor has three distinct vibrating intensities rather than a gradual increase as you turn the dial. The wire seems long enough for general use but could be longer. With the setting on high it can deliver some pretty strong vibrations too.
At one point when I was cleaning the rotor, I saw that a bit of lube had gotten inside where the two halves of the motor casing meet. I haven't experienced any change in performance since then though. It would be pleasant if this had a fourth intensity lower than its first since it can feel awfully strong at first. The noise made out in the open in near silence is also pretty loud so be careful.
Overall I'm definitely satisfied with this rotor especially since its a freebie.
From a free product, I expected the vibration to be extremely weak. However, it was much stronger than I thought. Goes great with any onahole with two holes. Put it in the other hole and enjoy light vibration..
Added to my order because it was free and lightweight & I've never owned anything like this before. I like the adjustable vibration strength, it's actually quite strong. The batteries are a concern though, they are a knockoff "brand", so don't leave them in the rotor when you are not using it, or use some better batteries.
Comes with batteries but would suggest using different ones as it seems shifty. Rotor has adjustable speeds so I put it in onahips for enchanced feelings. Wouldn't recommend to pull by the cord as you might break it
Expected garbage; turns out it was silver (but not gold)
I expected this to break after one use or so, but it so good so far.
Comes with non-brand, meme batteries (not sure if trying to copy the Panasonic logo or not lol), although I would advise maybe buying your own batteries for caution (bad batteries can explode, and no one wants a roasted onahole+wiener). The vibration strength is ok and you can adjust it with 1 hand.
The rotor itself has some imperfection (for mine at least), which could gouge your onahole if you aren't careful. Sand that part down or wrap it in a few layers of plastic wrap and you're good. As with all electronics, don't get the controller wet and don't pull the rotor by the cord.
