A part of the review has been auto-translated.
Nice product, I don't know how is working but is very sensitive, don't even needs to touch it, it starts whistling very loud even if you get 5 cm close. It hangs on my door handle and I find it very useful. I still don't know anything about the battery life but I will keep you updated.
Does what it says. And for the price you can't beat it. Would be good for use by females staying at motels and college dorms. This device is very sensitive and loud.
esta muy bien solo que deberían mandarlo con batería aunque subiera el precio
arrived and is as described. not used it yet
Nice product and Wow! it really works.
Nunca me llego mi pedido se suponía que me llegaría el 8 de Mayo y estamos a 31 de Mayo y me fue cobrado el día 2 de Abrilespero su respuestay mi pedido
superb loud noise but not that much effective as it's sensors are not perfect...
Looks good but is much bigger than I imagined.
The appearance may not be 5 stars, but the value is 10 stars. This thing is impressive with an incredibly LOUD sound and very sensitive to motion. The case and battery compartment looks cheap, but I was very happy after testing it.
product works as described
