Arrived without batteries

Very good product. I ordered 5 units. Quality materials. A great store

I checked one, it works, I will not use it exactly as it is intended-I.E. The coat of arms "I will distance", in the House Yard KSTA, the reed switch works on the circuit (you lift the magnet-closes) and it is +, because. For my task, this is an increase in reliability, namely, control the circuit from the signal to the Reed

have not tested

Without batteries, so the performance has not been checked yet.

Very fast delivery, recommend

Promptly delivery, work well and loud enough. Happy purchase

All five are working with batteries. Found an interesting way of installation-under the window frame, and the magnet replaced with a small flat, glued from the bottom to the frame. The switch moves by any plastic card. The food is puncturing enough, the bezels resonate. But passers-by and neighbors are unlikely to hear. The sound is aimed exclusively at nearby thieves.

As described. Recommend. Thank you store.
