Review on Groz 1550 Industrial Grade Compass: For Precision Navigation in Work Environments by Amanda Ellis

There is very little quality control in their manufacture. Both set screws are drilled and cut at an angle; one on either side. The pins holding the pen holder are pushed too far into the ring to accommodate round pins. They should have been pressed flatter or this piece welded on the outside. The curved part doesn't really match the arc of the tool hole as can be seen in the two pictures with the set screws removed. Both set screws were coated with grease and metal shavings. The photo I received was after I had already deleted 90% of it. "Powder coating" is really soft, more like spray paint than good powder coating. They stick, so making small adjustments to them is a bit difficult. I use them to mark circles on drywall for recessed lighting, they work great for my needs and are solidly built but they don't fit. t "nice".
