Anyone have any experience with the JennyPrinter Ultimaker clones? Seems like it could be a pretty good deal.

Why would a business calling itself “JennyPrinter 3D Research Center” be copying Ultimaker machines?
With a grand title like that I would expect them to be designing innovative machines of their own.
Sounds a little bit “Iffy” to me.

issues with the quality of the nozzle drilling
fan-duct touching the Olsson block
the PTFE reaching down into the nozzle
cracked plastic on extruder
noisy 5V fans
thermocoupler cable too short, can’t be fully inserted
spring is not strong enough
M3 bolt doesn’t go into the Olsson block because the hole isn’t drilled cleanly

there seem to be issues with shafts not being accurate
much better belt pulleys (the ones in both my original UM2 are not centered and thus leave black belt-shavings)
nozzles reported as okay (as opposed to the previous posting)
hot-bed has not enough power
