The Bear design has nice features, I prefer it to the original.
this is by far the best seller on AliExpress! The seller is exceptionally helpful and stand by this product 100% The quality is great, the finished product is great and prints come out in my opinion better than a standard Prussia i3 mk3. The bear firmware flashes perfectly and everything works. I had trouble with the belt tensioner and the seller sent me replacement parts to fix, but I was still able to use the printer during this time. you do need to be spot on with using the correct screws and it helps if you have assembled a printer before. point is you CAN assemble this printer with the public bear assembly and i3 instructions. you may want a few spare screws as others suggest but most problems is a mistake you have made and those problems can be fixed/reassembled. great seller and great product
