I've used this joiner on various projects over the last couple years, finding it functional and easy to use, but when I recently put it through some considerable work I was seriously impressed. I just made around 400 slots in order to build a half dozen chopping boards. It cut through both jatoba (Brazilian cherrywood) and maple like butter, making clean, consistent, and accurate slots. The blade is very high quality. The dual rack-and-pinion fence is very accurate, easily adjustable, and stays where you set it cut after cut. The gauge is easy to read, a plus when your protective eyewear is covered in sawdust. The preset stops make it easy to choose the proper slot size too.
