Came for 20 days to Moscow. How to connect, I'll add!
Received, delivered in 3 weeks. I put the crown, I put it on the alarm, it works. I haven't checked the smoke yet. Without the installed battery, the lid does not close, which is good. Instruction in English.
Ordered this product 2020-09-23 the product came to the branch "Ukr Post" 2020-11-03 the parcel came well packed, whole. The contents correspond to the description. I checked, everything works. Seller recommend.
Received, but did not check, I forget to buy a battery
as described
Quite a normal sensor, from similar is distinguished by the presence of a branded inscription and at the time of purchase by the price. In principle, for this money, there is nothing to complain about. Product and store recommend.
Quickly received W18 alarm connection without pb
Delivery to Tula region from Russia from warehouses Podolsk a couple of three days. Super fast shipping! The sensor immediately tied to the signal like it works.
Благодарю, все очень быстро, прямо домой, молодцы, сервис, даже не похоже на Россию.
Подключил к уже имеющейся сигнализации в гараже. Настроил без проблем на 93 зону. Рекомендую.
Всё приехало быстро, подключается легко, работает. Нужна батарейка Крона
I order it for the second time, everything is fine. The first time I ordered a little wrong sensors, but decided to leave. The second time ordered the linkage, everything is OK, the alarm was determined instantly. Pretty fast delivery, about 2 and a half weeks to VRN.
It came in 2 weeks, like norm. I haven't checked yet.
The sensor is large, connected to the alarm without problems. Smoke testing was not tested
Received the wrong product. Finally got my money back after a lot of communication and time with store.
Everything works. The sound is loud. The alarm hasn't arrived yet. I'll connect her later.
Very well meets my expectations
Everything works, settings-completely open, there are jumpers on the board, put on 0 next to the blue square with adjustment, still twist and everything screams as necessary, the battery of the Crown 9V
The letters are slightly pasted Krivo. I checked only one sensor, because there are no such batteries available.
