Upon opening the package I noticed that it was well packaged and arrived in great condition . The screw is tight, but not too tight. The sides of the clamp are slanted as indicated. I've clamped about 3/4" to 2" thick hardwood and it compresses firmly without leaving any marks and it seems to be held parallel. The mounting clip is also strong and holds up well. As an extra precaution, I bolted the vise base to the workbench through two mounting holes. This is temporary until I assemble a new workbench with thru bolts installed as instructed. I'll probably buy another one so I can keep longer trim boards.
