Battery life of wireless doorbell

[Dave Plowman (News)]

If you can't hear a bell throughout the house, why bother with one? Just have a knocker on the door - no batteries to go flat and no running costs.

It's such a one time installation worth getting right, IMHO.

Not a good simile. You find a notebook when you want to refer to it. A doorbell is needed at random. And it's such a random thing the idea of carrying it with you strikes me as silly. If you did need such a feature one which interfaced with your mobile would make more sense. Easy enough to do with an alarm SDI if you wanted to.

It's quite simple really, you don't want the doorbell so loud nearby, but also want to be able to hear it elsewhere, for a different door.

How would you propose to not "get it right"? You seem arbitrarily set against a cordless doorbell merely because you can't envision a use for your subjective purposes. That doesn't begin to make it a bad choice for a different, subject's purposes.

How it is random? Do you really not expect people coming over ahead of time, they always show up by surprise? Perhaps at your front door, but remember this is a separate remote button and may be at a different door- one where people showing up may not be doing so at random.

It goes back to what I already wrote, you just don't envision a use for _your_ door, and you might be quite right about it... but that doesn't make what someone else chooses to do any less useful to them.
