So far after nearly 4 straight days of printing, I'm very impressed. There were a few minor issues right after unboxing. Fast responses from 3dprintersonlinestore as well as weistek.
I've made objects of all types and sizes. There is a learning curve to 3d printing. Things that seem simple if you have experience, such as adding supports to suspended parts of a model or using MeshMixer to modify objects won't be obvious to the average consumer.
Not understanding how 3d-printing works will leave some purchasers upset when they end up with a wad of filament, or a clogged extruder. These types of things can happen on any 3d printer no matter what you pay for it, or what brand you buy. Sometimes it will be the fault of the hardware, but is more often caused by the user not understanding 3d printing concepts and limitations, and creating a mess (I've been there and done that).
