Pretty poor courier service - tracking function is very limited, with no pre-warning when delivery will be made, other than on the morning of delivery, which is not much help if you have no idea when to expect the delivery. The delivery slot is 9-5, which isn't very helpful for people living in the 21st century that can't be at home all day. No option to change the delivery date or location without having to call the company - I called the general inquiry number, held for about ten minutes, then was told I needed to contact the local depot instead. Unlike many other courier services, there's no option to pick a parcel up from a collection point, other than their limited range of personal depots. Compared to a lot of other courier services, DX seems very limited and out-dated. I wouldn't use if you have another choice.
