This tool has done more to improve the quality of my projects then anything else I have purchased. The knives are relatively easy to adjust. Overall I have to rate this tool excellent. I did add a set of wheels on a hinged board on one end to make it moveable. On the in-feed end, as picking it up from the out-feed end probably puts less stress on the tool. I will probably get around to adding another set when I have time. The tool is not built or sold as portable, so you really can't this against it. Kinda pricey, but worth it.
