Quality:
Everything in the kit was neatly and securely packed. Everything was in perfect condition when my order arrived, except for the floor tom rim. It was broken on a point very close to the tension rod hole. But Thomann replaced the item with a new one without hassle. I didn't even need to send the broken item back, they just sent me a new one. So, many thanks to Thomann team for their awesome support! The plastic parts look a bit flimsy, you should use them carefully. If you don't be gentle on the plastic hardware, if you tighten the rods too much for example, or if you let them lie under sunlight for a long while, they might break. Other than that, rack system, cymbal & hihat stands and the bass drum pedal is decent quality and useful. You won't need to replace them.
Sound:
Whole kit sounds surprisingly good. Especially the toms... Bass drum feels a bit shallow as it has no shell obviously; and the snare drum is like a small piccolo snare. But neither of them is a problem especially if you have the chance to mic your drums. A good tuning and some simple eq adjustments can give you surprisingly pleasant results. Of course, expecting a full range rich maple shell sound out of this kit would be ridiculous, no need to mention...
Features:
The best thing about this kit is its portability. I suggest you to buy the bundle with the softcases as it makes everything a lot easier. You can carry your drumset in just 2 bags. You don't even need a car any more, you can go to work by bus or almost any other transport :)
