The buttons click a lot, you have to tap them properly if you want to do something on time. Jogwheels have a bit of a compatibility problem with NI Traktor, you have to look for fixes/patches on the net to make it work as it should. And beware, this is primarily a MIDI controller and sound card, not a player per se, so this wav/mp3 won't play. It's a good choice for a beginner.
