Has anyone experience with the chinese UM2+ head? It is less then the fifth of the price of the upgrade kit.
It's a hit-or-miss game buying parts from China...you may get lucky and it is of decent (still not excellent) quality...but most of the time you will find that the quality is crap. A quick search here will reveal many posts where you can see how bad they actually are.
My 2 cent advise is to either buy the official parts as @ultiarjan suggested...or look on eBay et.al. for people selling of parts when they have upgraded their UM2 to UM2+ (that is how I got hold of two printheads in used, but very good condition).

If you only want the head just buy the original parts you need. You can order loose spare parts at ultimaker2 resellers. Just send one a mail with the parts you need. You can find all partnummer in the BOM on the ultimaker GitHub page. In my experience the dimensional accuracy of AliExpress parts was not great.
