Review: Good quality microcontroller based circuit.. But, the power supply side is not contain power transformer. Just a simple capacitor based supply so there is NO Galvanic insolation from mains !!! So if the power supply side is fails , it harm the bell. NO SAFETY FUSE in the mains line! No Mov (Metal Oxid Varistor) across the phase and neutral. Dangerous!
Review: Phone matches the description, to Moscow reached 1,5 months there was a delay sending due to the holiday in China. both call work out of the box, did not have to configure, the call is loud enough. button battery included. the only minus button closes the lid tightly. in general, I recommend!
Review: Well packed parcel. although the box was crumpled, call does not hurt. to Novosibirsk 24 days. track to track. the quality is good. ring is excellent. the sound is loud, with the ability to adjust. I advise product and seller!
