I think possibly the issue with MB stuff is that when it does break, getting it fixed is neither easy ( Only 1 repairer) nor cheap ( usually need to replace the power supply module). That said I've had MB stuff since it came to this country in the noughties(?) and only needed one *repair when I dropped a LM2 in its case. Luckily under warranty so FOC. Since the LMII, I've had an LMIII, an 802 combo, a 801 combo, a TTE 500 and cab, a NInja 102P 250 combo and currently a 101 MM Combo and a CMD101P and NYC 121.
* Just remembered on the Ninja 250 the fan was noisy but out of warranty so I bought one from Real Electronics for £30 and fixed it myself.
