Great design, let down by some poor quality
This tool seems to be a great idea for conveniently setting & firmly holding those awkward 90-degree corners before the panels get glued or screwed together.
The design of this tool is impressive, and the quality of manufacture seems good, except …
1. The resulting angle of clamped panels is consistently 89.1 degrees, not 90. Sounds trivial, but this is 3/16" error in 12" which is unacceptable. The angles of both the internal clamping block and its mating external frame have the exact same error (as measured by digital gauge & confirmed by eye with a square). A quote from the website: "The clamp’s V-wedge jaws grip the mating pieces securely, ensuring that the pieces sit at precise 90° angles …". Not sure what went wrong there (I can see no signs of damage). But because I know that the rest of the tool is quality, I will probably try to file down both parts to get exactly 90 degrees (or add packing pieces?).
2. There are no proper instructions. While the packaging shows some pics of how it can be used, the impressive "AutoMaxx" clamping system in particular needs some explanation because it needs to be properly setup. In any case, for the money paid, you would expect detailed instructions to be included - and they don't seem to exist on the website either. And there’s no warranty information.
It's such a pity about these 2 issues, because it is obviously a well thought out tool, & I'm confident it will be one tool that gets a lot of use (that is, after I make some necessary corrections).
