Query: Don't waste your money

I purchased this item expecting to be able to use it on a job that required pre-hanging a houseful of doors. I was very disappointed. It would not perform even to minimum standards and I had to purchase a different brand of jig in order to complete the job. The plastic houseing was of very poor quality. I would recommend anyone considering this item to re-think their purchase.
