Works well but remember to REMOVE the grommet and screw before installing the sender unit battery
I chose this item over cheaper alternatives because it looked better .. black and a bit a chrome finish .. the others appeared to me to look cheap and plasticy in comparison. Now a door bell is something difficult to be positive about isn't it. However, it's arrived, looks good and works. A word of advice. Before attempting to open the sender unit to put the button battery in be sure to REMOVE the rubber grommet under the perspex lid and REMOVE the screw underneath it .. otherwise the unit won't separate and will just break. The instructions with the product are poor on this detail which is presumably why the retailer has added some extra instructions about this on their Ebay site ... after that you've got a lot of tunes from which to choose ..
