A basic flaw in manufacturings renders this thing useless: it cannot be opened and reopened because the threading on the cap does not fit the base unit.

I'm the marketing director for an A/E firm. Thought this gizmo would be great for presentations... I ordered 12 of them to give to all Partners and Principals in the firm. Much to my embarrassment, the unit I retained for my own personal use literally came apart while I was trying to access the flash drive. Bottom line - the metal device has been cheaply glued in areas where it should have been permanently soldered. The laser pen works well, the flash drive seems to work just fine, and the pen certainly writes, but I've had to tape the unit back together where the glue has failed.

Good product for the money; . Laser pointer is on the same cover that has the flash drive- once you plug it in, that's it. You can't use the pointer! (I suppose you can transfer your presentation to the hard drive and remove the flash drive- then use the pointer). Also, the flash drive base is the pen cap- it is slightly bulky. If your computer has a narrow space to plug an USB flash drive into.. good luck! An extension port solves this problem.
