Very poor quality ! Mine has broken in less than a 6 month. It produces a very annoying noise which will ruin your whole drumming experience ...
Things can get even worse when you contact the customer service to use the Warranty ! The Warranty process will make you forget about using the Warranty ... They will ask you first to record a video to show them its broken ... then you will need to wait 48 hours going through a hierarcy of support to ultimately tell you that you need to take the responsibility of sending the product in a special packaging to them in order take care of it ... So they actually fuck you twice, to get your drum working for you!
I do not recommend this drum to anyone! They are not sure about the quality of it themselves ;-)
+ the customer service is likely to be a simple auto-responder with pre-defined responses ... This will be the most annoying process.
