Truly lives up to the rating, if anything, it should be lower. Delivery driver didn't even bother ringing my doorbell, and drops a calling card in instead. Pure laziness if you ask me, it really isn't hard to ring a bell and wait a few seconds, it's more effort to keep redelivering, taking a photo in front of my door and writing me a missed delivery card. I had to call the local depot myself and explain that the same thing had happened 5 times, and they were quite understanding, going as far as to call the driver to reattempt the delivery on the same day. They also noted the delivery notes where it said to ring the doorbell, knock or call my mobile (I had these updated on the delivery notes prior as it had happened so many times). I have had to cancel plans and sit at home waiting for this delivery 5 times. When I met the driver (Scott), he told me he does not work 12 hours or get paid enough per delivery to have to wait for someone to answer the door. He insists that having done this job for 25 years, he knows how to ring a doorbell, so I suppose the doorbell that has been working all this time (including days where I have been sat at home waiting for the delivery) must suddenly decide to stop working when he presses it. He must have magical fingers that momentarily break electrical circuits, or weak knuckles that are not able to withstand knocking a door. Since he claims that the doorbell doesn't work (it definitely does), I assume he has not been able hear the bell ring from outside on all his previous delivery attempts. If that were the case, I imagine the next best course of action that would cross the mind of anyone with common sense would be to knock. Or perhaps myself and my housemates become deaf as soon he comes near the door? In conclusion, I suppose this will remain a mystery because there didn't seem to be a doubt in Scott's mind that he is faultless and does his job flawlessly, my account of events would probably differ. Don't use DX, what a waste of time and money.
