So far so good. Ordered on Tuesday night, delivered Friday morning! It's quite a bit smaller than our last one, a peavey 16/4 from about 30 years ago, about half the size. So we'll see if this lasts as long as that one... The build seems pretty sturdy, thick plastic for the frame and drum, though the centre (where the connections are) and rotating parts are all metal. XLRs all seems good quality. Cable is pretty thin (14mm instead of out old 1") though I knew that before I bought it. Hopefully it will stand the test of time. The part that splits out also seems good, with a strain relief that can be hooked onto other equipment. There is no way of fastening the cables to the drum for transport, so I'll have to construct something with velcro myself.
As the sizes aren't given on thomann, it is H35cm, W32cm, D20cm. My packaging also said it is from this company: had the following written on the packaging '30m MTS-TR 16/4 Amphenol, Schill GT310, 94002-30'.
Only 4 starts, as I have no idea how long it will last. I'll come back it 20 years to increase it if it makes it that far ;-)
