3D printer Heaterblock Ultimaker 2 +

Anyone here on the forum that already has ordered this part from Aliexpress? It's a dual heaterblock. See description Aliexpress: 3D printer Heaterblock Ultimaker 2 + UM2 Dual Heads Extruder Olsson block fans kit Nozzles 0.25--0.8mm HotEnd for 1.75/3mm.

Is it working good ? It is still for 2 days 40% cheaper in price.

Not recommended to do dual printing this way.

The reason is:
If it's manufactured perfectly the nozzles are on the same height. But that's not good because your 2nd nozzle will ooze on your print while the 1st is printing and vice versa.

For this reason all dual head concept work with two heads or with a lifting mechanism for the unused nozzle.

And likely the two nozzles of this head have a slightly different height  and that's even worse. Because then the lower nozzle would actually end vertically "in" your print and scratch it during printing.
