It's difficult to work out how much multicore I managed to wind onto this drum, but I can tell you it's VERY heavy now so I will be fitting heavy duty castors to the drum. It would be good to have heavy duty castors factory fitted since it will always be extremely heavy. Mind your back... filled with cable it needs two people to lift it!
The second flange, which is to allow winding out a tail is very much larger than needed for that, and I would have preferred a much smaller side tail flange or a larger diameter in the side flange.
There is no way to easily fit a multicore connector to the side of the drum which is also sad. Build quality is good, so even heavily loaded I don't expect it to break.
In the past I have always used cable drums from Canford Audio. These are significantly better designed and engineered, but the price reflects that, which is why I bought the Millenium this time! In bang-for-the-buck I'm happy with the drum -- it is good value for money if not the best quality.
