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 10" snare/tom pads; the red wire going to the pad's main piezo (component that senses stick hits) keeps breaking during use. Over the years, this happened over 10 times in 5 different pads (the 3 originals + 2 replacements sent via RMA process). You can tell it has happened when pad sensitivity starts decreasing dramatically, or disappears outright. You can 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.
Sadly, eventually the cables break too close to the piezo to solder back, and it's impossible to reach in to replace the cables without detaching the piezo. The adhesive holding the piezo is single-use and after it is replaced, the pad no longer works (is unusably quiet). So, the pads and by extent this drum kit came to their end all-too-soon. Thus, I lowered my rating accordingly.
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.
Millenium should address the simple design flaw in the tom pads to dramatically improve the user experience and reduce e-waste. The manufacturer probably saved some pennies by using garbage quality piezo cables, and as a result everyone else is losing hundreds of euros.
