7 Dec 2020 07:39 Delivery to Ukraine is less than a month. Packed well. Batteries in stock. Everything works. Very loud. The only small minus, fastening only on double-sided Scotch.

24 Nov 2020 22:10 Order received. Unpacked, I did not check in the work yet. The packaging is very flimsy, but nothing has been hurt. A little later I will add a review, how to check in action. The goods look solid... |
