As far as strength, all tow bars now need to be tested, so if they are not up to the job, even the cheap ones they cant sell them.
Yeh, but.... I had one of these on a car. It had all the relevent markings but it was bent to buggery. Looking at its construction, it was far too lightly built.
Look well at the construction and estimate where the loads are. Look at the position of the welds and the sections of the metal. Imagine what the loads would be if you, your car and trailer got pear-shaped. If you reckon it would all stay together, buy it.
This wont apply to your Disco but, generally, if the towball mounting flange is butted against a piece of square tube and simply welded around the back, walk away. This construction is common place and it places the whole of the towing load onto that single weld. I once saw a motorway accident where the towball and its mounting plate were still attached to the car. The caravan was on its side across the central reservation.
