David 3 The tool works well and is much cheaper that's the real tool. I would like to see a bunch of extra bits, but I can buy them elsewhere. The silver guid rods are very poorly designed, I think horotec cuts a groove and installs an E-clip on each end of each rod, this cheaper version glues on and metal cap. All of the fell off during shipping, haha. I tried to press them back on, but the glue was too hard. So I don't have the end caps anymore. I'll have to try and get the grooves cut for e-clips like the real tool. Until them, don't extend too far, haha. Also the black plastic handle won't stay tight.
