K8200 ROD issues

The rods in my k8200 kit was not correct diameter
I was very disappointed when I saw and measured the rods they were not the correct diameter they should be 10mm but was 9.5mm and 8mm but was 7.8mm so you get a big gap in linear layers is this correct?
Or have you lost the quality check of your products?
Wishing u send me new rods

for broken parts
