BAOFENG BF-UVB3 Plus 8W UHF / VHF Dual Band 3800mAh - is it all that good ?! A lot of photos!

I asked an acquaintance to buy radios for work, before that I took UV-5R, but then I decided to take him more effectively, thanks to the coupon, the difference was not so great. That's what came of it ...
Made a purchase, asked the seller to pack it well, to which the seller pleased me, said that the radios would be sent from a warehouse in Moscow.

Gave the tracking number IML express and after 4 days, I already got them.
Characteristics from the seller's page:

Baofeng walkie talkies are shipped in such boxes

Inside is a walkie-talkie


Battery

Antenna labeled Baofeng U.V Antenna FM / 136-174 / 400-520MHZ

Headset

Docking Station and Charger

And also a lace on a hand and a clothespeg for fastening on a belt or trousers.

The battery has an input for charging 4.0 * 1.7 mm
I rang it, apparently there are no charging controllers inside.
Since The tester squeaked both at the inlet and at the outlet and at the charging socket.

I noticed garbage on the display in one of the radios under the glass, there is nothing to do, it is necessary to open it ...
The radio understands easily:



Differences from the UV-5R perhaps only in the case, the buttons that are made by a separate board (made in the form of films as the keyboard) and the number of elements on the board.
Unfortunately, I don’t have any instruments for measuring signals, but judging by the board, it is already possible to conclude that there are no 8Ws in it, which means that this is some new clone UV-5R in the new package.
UPD: Made a test of communication with a friend, a distance of 1.2km at the intersection of 12 houses.
