This drum has way more cons than pros, so let me try to list all of those found after being a regular user for 2+ years:
Pros: Possibly the cheapest set of electronic drums out there; wide gamma of built-in sounds and rhythms. Cons: There is no rim sound in the snare nor in any other pad; the hi-hat pedal has a terrible response; the pads are all sustained by plastic parts which can easily break after a few months (the plastic holder for my cymbal broke after 7 months); it's a very fragile kit, so it's not easy to carry from one place to another; the phone plug can also get damaged after a few uses since the module is part of the plastic structure of the drum and it just moves around with the whole kit while you play it.
If you have any extra money and you still want a cheap drum, please save it for a Roland HD-1 or HD-3 or even an Alesis drum kit. Don't buy this, you will certainly regret.
