The goods are good, I'm happy, loud in the room, on the street is normal, squeaky, you can muffle if you close the output of the speaker with Scotch tape or or Ordered 2 pcs, one working, the second without a button, defective, money the seller immediately returned.
Delivery to Tver Region 2 months. Such a signal was bought already. The former was with a battery cover on a small screw and a very thin ear that immediately broke, I had to collective-farm wrapped it on the self-cutter. On this cover on the latch but also not very strong in appearance, so be careful when opening and closing. There are no other problems, the signal is loud enough. I recommend to buy.
The sound is excellent. Touch others cool!
