Cons (-): Batteries are difficult to insert and hard to take back out.
The sound is not as good. The vibration is much to be desired (too weak).
Conclusion: Pricewise it is a good product. But one should look out for when processing it,
that you can insert the batteries lighter and again are easily removed. Furthermore, you should
the vibration a little increase, because it is weak. At the sound should also work, it comes out louder sound, well in advance, but the quality of the sound is bad. So on the whole, one can recommend it.
That's why only 4 stars.
