I bought the bohning jig about 2 months ago and havent had any problems yet. Does a good job on right hand helical vanes and blazers which is what i mainly use it for. The directions are so so but for $60 for the kit you cant hardly go wrong. Take consideration I only used it for myself and my family. I am sure there are better jigs out there but for the novice it works fine. Takes about 5-10 minutes per arrow depending on what glue you use.
