Delivery was carried out by 5Post Company. As a result, my parcel was opened and spiced exactly half. Got only smoke sensors, all ordered 6 pieces of leak sensors "gone" in an unknown direction. The seller "twists the tail" in communication, maximizing the duration. Answers once a day, carries some nonsense. I can not open the dispute, I constantly write "system error..." Delivery was fast, literally in 10 days delivered the rest of the parcel. The true weight of the parcel sent was 674 grams, and in fact received only 310 grams, but it did not confuse anyone but me.

Incredibly fast delivery to 5post, though I found out about the delivery accidentally checking the status of the order, Pyaterochka forgot to send a notice. Power the sensor from 2-AAA batteries. In the kit they are not, of course. The body of the sensor is supposed to be glued to the downside Velcro

Sensors quality. Through Tuya pairing without problems. All functions work. Battery charge Show (connected 2 PCs battery 1,2 v 1000ah). I am very pleased with the purchase. I took it for a test. Good store, quality goods with resonable price. I recommend to buy. Thank you!

The parcel went a month to Ukraine. at first glance made soundly. works from two Pinky batteries (AAA 1.5V), not included. In the rest, everything as in the description. in the work has not yet checked, but I think there will be no problems. I hope will last a long time.

Thank you seller. Put the instruction on Russian! It's just a respect. Everything came quickly and one parcel (ordered several goods from him). I'll check, and complement the review. But everything looks very good. Everywhere power supplies put with Russian plugs!
