Amazon Customer 2 I ordered this product for its price and it seemed like a decent product. I also thought even if it's not so good, it's only about ¥3000. However, this is not even worth that much. I wouldn't even spend ¥1000 on it. The two most disappointing things about it are its battery life and vibrations speeds. First, there are 6 speeds as advertised, however the speed is really REALLY slow. If you want it to go faster, you need to push it against your body a little, but not too much or else it will stop. Second, I charged it overnight (about 8 hours) and when I woke up this morning, it wasn't even fully charged! I used it for about 5 minutes before it died.I usually don't write reviews, but this product is the worst product I've ordered so far. I wouldn't recommend this product even to my worst enemy.Edit: Their customer support was good, so I added another star.
