Product Review 0002: Wireless Doorbell with Receivers

Review of the Wireless Door Bell with Receivers

What I dislike about typical door bells is the need for lots of D size batteries (4-5 pcs) and that the door bells cannot hear in bedrooms as it is always near the door.

So one day, I was surfing the internet and came across this China-brand wireless door which you can add on receivers. This means that if you have no limited budget, you just require one door bell and put one receiver per room. I decided to give a go to see if it is as useful as described by the seller.

Advantages as advertised by seller

• Wireless
• No need for batteries
• Simple set up

Unboxing and Aesthetics

The outlook of the box is like how a Xiaomi product looks like. The box is brown in colour and the items are slotted into the cardboard casing.

The first thing you see in the box is the receivers, which I purchased 2, 1 for the living, and another for the bedroom. Below the receivers is 2 travel adaptor plugs and what I presumed was the bell as there was a bell logo on it (duh). I initially thought the seller was kind to give free travel adaptor plugs until I realise it is for the receivers.

The receiver looks like a night light with the two flat pin plug head at the back (typical of China products). As the item is not distributed by Singapore seller, there is no safety mark certification so it really is used at your own risk. The voltage is from 110 V to 240 V, just like our normal phone chargers. There is also an instruction manual included but it will not be necessary at all.

Installation and Using the device

I simply pasted the doorbell on my door and plugged in the receivers, one in the living room, another in a bedroom.

When you depress the doorbell, there is a pleasure blue light that emits from the bottom centre of the doorbell. The receivers also respond almost instantaneously as the traditional “Ding-Dong” srings just as you press.

The only annoying thing I find is that the receivers will immediately give off the “Ding-Dong” sound whenever you power it back on (I do off the receivers when no one is home). The receivers are normally in sleep mode when the doorbell is not working, so I do not face any overheating issues thus far.

Conclusion, this is a worthy product if you are not particular about Safety Mark

What I like

• Ease of use
• Adjustable bell volume
• Wireless doorbell

What I don’t like

• No safety mark on receivers
• Annoying sound of receivers whenever I power it up
