I opened and assembled it, but I've only used it a few times, so it's almost like new. The Donner DED-80 is an ideal electronic drum set with everything you need. It comes with an adjustable dedicated throne, headphones, and even drumsticks. This electronic drum set is suitable for children as a gift, as well as students and adults who want to practice easily at home, with a minimum height of 90cm to play. It has 180 built-in sounds and 15 drum kits. It reproduces the realistic and dynamic drum sounds of a drum kit. The more delicate and high-density DED-80 mesh pads, compared to conventional rubber pads, have a stick rebound that is closer to the feel of an acoustic drum, allowing for more realistic practice. It's perfect for practicing at home because you can connect headphones. The drums are foldable, so you won't have trouble with portability or storage space.
