YOTINO 14Pcs/Set Including: 6 Pcs 3D Printer Nozzle Throats + 6 Pcs 0.4mm Brass Nozzle Print Heads + 2 Pcs 0.4mm Cleaning Drill Bits Compatible with All 1.75mm PLA 3D printer for MK8 Makerbot Reprap

Everything else in the package does as you'd expect and is easy to install, but the cleaning bits are very brittle, one of them broke off into the nozzle I was cleaning, causing me to slip with it and lodge a shard of the bit into my thumb. Be very careful and gentle when using these. Otherwise, good product

Great, just as described, good value and prints well on my A8 :)

Just as expected, no remarks and good quality.
