I love my Ender 3 with the Duet Wifi...it works great and now greatly out performs my Taz 6 printer in both speed and quality. Granted...my ender 3 is far from stock using a geared printable extruder first was using a Greg's wade bowden variant and now one called the Pitan, linear guide for the bed, polycarbonate v-slot wheels on the x and z axis as well as dual z rods and stepper motors. The thing is so reliable now, just set and go.
