Disappointed
This tool was a real disappointment, the first thing I noticed were two screws holding the twist mechanism in place which was an obvious after thought. I could easily live with that but as I began to drill dowel holes I discovered that the white marks on the tool that were needed to line the tool with the project did not extend all the way to the bottom of the jig thus requiring a certain amount of guessing. Still, something I could probably live with but when I drilled the holes and the self centering jig did not center the holes but was anywhere from a 32nd to a 64th of an inch off, (requiring the jig to be rotated to the other side and a second hole drilled in the same position but on the opposite side) I became disappointed. I was going to return the tool but the company, Grizzly Tools, has a very rigorous return policy requiring the tool to be returned in the same condition it was received, impossible if the tool is used. Moral of the story, I will never buy from Grizzly again.

Good stuff at a good price.
I just received my jig and was immediately impressed with the simplicity and quality of this unit. I would expect to use this for a very long time and experience excellent service from it. For the price, you can always ask for more, but this is of the highest quality you can find any more and is well made. For the price this is a very good tool! This is a well made, clean, simple, easy to use tool fo high quality materials!

Thanks Grizzley for a good tool.... that makes 3 good experiences in a row for me with Grizzley. I look forward to buying more with the Grizzley tool name on it in the future.

Works well, with sufficient care
The title says it all. I've made a bunch of joints with this jig and they almost always turn out very well. However, there are a few things to watch out for. The piece you're doweling really needs to be clamped. When you tighten the jig around the wood, the clockwise rotation of the clamp will sometimes turn the jig slightly on the wood (clamped or not), giving you a slightly non-perpendicular hole; double-check this before you drill. It's sometimes a little difficult for me to line up the jig's marks with my own marks on the piece, but again, with sufficient care, it works fine. The manufacturer recommends using brad-point bits, but I've had no trouble with regular bits. In short, the jig is very helpful and can be used to make great joints, but you need to take your time and use some care.
