This gadget is already a bit mysterious. On one hand, it does what it should, on the other hand you have to wrangle with Zirp- and Quieckgeräuschen. I still have not figured out why they occur. the first device I have even sent so back. Is it the pairing process or some "energy flow". So far, it occurs irregularly. Since I can not forgive only three stars. Amazingly, that was not mentioned in any review. Annoys me the animal and I do not send it just because of that back, because I still want to get out, why it chirps and quieckt.
For the actual task, the sound can say: Yes, work. For me it is intended to improve the sound of it standing Tablets and it works. However, there is no sound miracle, too loud and there are limits audibly. Would I buy it again, do not think so ....
