The best things about this wireless doorbell are the price and the volume of the chime - I can still hear it when I am having a shower!
There are sixteen chimes in total - including a few Christmas ones - so great for the children to play with at festive time. Unusually, the chimes are selected by a push button on the side of the unit, rather than having to mess around with the usual jumpers or DIP switches.
The addition of a socket outlet on the front of the unit is an added bonus but it is very stiff putting a plug into the socket, so I would recommend that the unit is used with another device that you want plugged in all the time. I would also suggest that you want the unit at a higher level (rather than near the floor) as this not only improves the already excellent range but prevents the unit from being damaged when cleaning the floor etc.
Overall, I prefer these plug-in units to the battery models as I usually forget to change the batteries, but It would be nice if they made a unit that was actually rechargeable, so that it could be taken with me when I am outside or in my shed.
Have a look at the other TeckNet products on Amazon - most of them get very favourable reviews and they have a very good range of unusual but useful devices! I will certainly be shopping for TeckNet on Amazon again
