I have one, Bought from FLO recently. I had some backlash issues with the Dec Axis, You could rock it backwards and forwards very slightly but it was audible. I had used a Cheap SVBONY SV205C and pointed at the moon you could see the "mount" Stepping during tracking. Spoke with FLO who instructed on how to adjust the backlash on both RA and DEC, Bit nervous as this is my First go to mount and you have to remove the plastic clam shell and a motor to get to the adjustments. Anyway all seems to be resolved. I have a couple of sample videos of the tracking a star with a 3 x Barlow and the SV205C after the adjustments and one with out the Barlow.
3 X barlow
Without Barlow
This is what I was getting before adjustment
