Review: Overall would purchase again, but both units have annoying clicking sounds from the bearings. - The products arrived intact and functions according to specifications. However, there is an issue with clicking noise originating from the non-drive side bearings on both parts. After careful examination, I have verified that the bearings are not constrained by any mechanical interference, even after loosening the end blocks. It appears that upgrading to higher quality bearings is necessary to resolve this inconvenience.
