Review: There are plenty of tension rods out there. The _only_ advantage of the Umbra rods is that they look better. (Why other manufacturers haven't figured out the design part is anybody's guess.) The problem with the Umbra rods -- all of them -- is NO tension. I have tried these repeatedly.... Why? Because my local hardware store carries them, and they are readily available elsewhere, and I have opted for form over function. Every single Umbra rod I have used fails drastically. They simply cannot bear any weight. Or, to put it differently, they cannot exert enough force against the surfaces they extend out to for them to bear any load. Worse, the springs that are the key element in sustaining the tension tend to fail. When those springs fail, anything you have suspended by the rod will come down. If it's a lightweight drapery panel, you may be in luck. Otherwise, forget about it.

Review: Great picture quality, cool, and Blu-Ray is the premier format for all of its seamless feature interaction, and high storage capacity for more bonus material.... except Spider-man 1 and 2 have no special features (aside from the 2.1 stuff). Great use of space, thanks for all those perks, BR.So, I have to wonder, is it really worth the $70 to pick this up again?

Review: Received this in great time- I have no problem with the seller:-)BUT! The inside of the case lists all types of materials this can cut including metals, which is what I got it for.One punch through soft 26ga copper sheet and the edges of the punch bent & in some areas, flaked off. The second disk I cut did it in completely. I had to file all of the edges and it probably would have been easier to cut the sheet with shears.So, not for metals.However, I can see it would be great for leather, paper & plastics.To me it was worth the money spent on the chance that it would actually cut metal disks.
