I opened the box and set this up yesterday.  It was packed about the best I have ever seen any tool packed for shipment. Assembly consisted of installing the table, with two hex-head machine screws, and adjust it slightly side-to-side to center the blade in the hole. The ends of the blade clamp screws were already centered and perfectly flat, so I didn't have to file off any burrs.  When a blade was installed, I only had to adjust the table tilt a bit to get the blade perpendicular and it was already perpendicular front-to-back.  Then I set about to cut 23 rings out of 5/32-thick laminated boards I am using to make a bowl. The saw is quiet, nearly vibration-free, and efficient, and being able to raise the upper arm is a real help when inserting the blade through a tiny hole in the workpiece. Blade tensioning is easy with the tensioning lever right in front of the upper arm.  No information about durability yet, but this saw was perfect right out of the box.
