I finished assembling this about 30 minutes ago, and I wanted to point out two specific errors in the instructions, both in step four:
* The dowels to be inserted into the upper-right part [in the drawing] of DIVISION (E) are incorrect. This will be obvious by the fact that they'll go into a hole for the cam bolt. Ignore the instructions and use your common sense: if it's got a space for a cam bolt, a dowel doesn't go there. It is unfortunate that the dowel holes and the cam-bolt holes are the same size: as the night wore on, I mistakenly put dowels in cam-bolt holes with alarming frequency.
* They have you fasten the BOTTOM RAIL (G) upside-down. This is clear from the seemingly impossible instructions to use the Chipboard Screw (4) to fasten the bottom rail to the divisions (E). It will become even clearer in the next step when you attempt to fasten FRONT RAIL (F) and the dowels don't match. Turn the bottom rail upside-down, fasten to the divisions using the dowels and the Chipboard Screws (there isn't a pilot hole for them), and you'll be good to go.
Everything else in the instructions is correct. I didn't have any issues with the hole designations for the drawer slides, as another reviewer remarked. The pictures are somewhat small; pay close attention to how they denote orientation by illustrating various holes and marks, and you'll get things in the right place.
A cordless screwdriver is recommended, especially for the daunting number of cam bolts in step one. You will need a stubby screwdriver or hex wrench to get at some of the cams once you've fastened FIXED SHELF (D).
All in all, a very nice looking piece. It took me 3.5 hours to assemble, and I'm a bit of a slow worker.
