BLACK OLIVE® Cordless Calling Remote Baoji Door Bell For Home, Office, Warehouse And Factories

So I bought this due to my Granny’s old condition. As it’s practically not possible to be with her 24*7. I bought this, and was really worried how it’ll work as I saw the other reviews as well. It’s been around a month, and is working like a charm. I live in 3BHK flat, i have tested it every way possible- from main door to end balcony; tried closing the doors etc. It wotked. She uses it freely, and we’re able to be available for her anytime now when she desires. Now coming to tech things- * Ring type can be changed, but not the volume. It’s as loud as enough though. * There’re 3 cells used.. 2 pencil cells (not provided together, have to purchase separately) and one small size pencil cell (provided in pkt). So that small cell would be a slight challenge to purchase in market, but can be found online. * Make sure not to paste your bell/call button at metal place. Use wall/wood/glass (non metallic area). Else cell might get week faster or machine can be harmed as well. I’ve got enough in around 300 bucks. Need more than that, then go for 2-3k item instead. No use to purchase lower than that, honestly.

Very useful...especially for a big house / an invalid.However there seems to be a design fault...it sometimes rings without having been pressed.It has limited range.

Forced to change review after 15 days of receipt, as it started malfunctioning. Automatically it started ringing without pressing bell.

Not a good product. Build quality is very poor. And the sound is terrible. But I guess its barely ok since it is cheap in price.

Have not used it sufficiently long to assess durability.
