content: Purchased this unit as a gift for my father. I am very impressed with the unit. The drill press is plenty powerful enough for a home workshop and the variable speed pulley system is great. We have not had any issues with the spring coming undone and it looks like they might have redesigned the spring clip for the pulley. I only have two negative comments. First in order to lubricate the pulleys you have to remove six screws. It would be better if they had a hinge and quick release. The second issue was in the packaging and shipment. The box came destroyed with the styrofoam in several small pieces. The unit was not damaged and I fault the carrier for this issue.Overall a great unit and I am very impressed with all that you get for this price.
