MPS-850 E-Drum Set : Unparalleled features for the €, but soldering skills recommended

A kit with a full-fledged hi-hat stand, 4 tom pads and 2 crashes, and a module with 2 extra inputs for this price? Yes please. The last part is the main reason I still haven't "graduated" to Roland – I already use Y-splitter cables to add 3 more cymbal pads from my earlier Alesis kit (replacing 3 tom rim zones in this kit). Affordable Roland modules only have 1 extra zone input.

A main design flaw in this kit is in the 12" snare/tom pads; the red wire going to the pad's main piezo (component that senses stick hits) keeps breaking during use. This has happened to me 5+ times now in 3 different pads. You can tell it has happened when pad sensitivity starts decreasing dramatically, or disappears outright. You can of course RMA the pads and get replacements, but after those broke too, I got fed up with the waiting and the mounting e-waste, and just soldered the cables back. Much faster and more ecological too.

Less commonly, the cymbal pads have sensitivity issues too, but those I haven't been able to diagnose, as the internals seem fine. Simply unplugging and re-plugging the pads often helps.

Overall I don't regret my purchase, but Millenium should address the simple design flaw in the tom pads to dramatically improve the user experience and reduce e-waste.
