Example Input: 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.
Example Output: Negative

Example Input: Now my daughter will not stop aggravating me because we cannot download the pictures off of the dran thing and wants a new camera, so now, I have not only wasted my money, but I have to buy her a more expensive camera that will work that she will break or lose.Thanks so much Vivitar!
Example Output: Negative

Example Input: I bought the ZR45MC camcorder in Sept '02. I have been using it quite regularly. then all of a sudden I cannot load new or old mini DV cassettes. The moment I load a cassette, a message flashes on the screen 'REMOVE TAPE' and beeping sound is generated together with a flashing 'EJECT' message. Next step, I ship this to the Canon Factory service in NJ. They replied with an estimate of $160(on top of the $654 I pad for this!!).Also most importantly when I shipped from the Fedex office in Boston, the Fedex person made a remark that she has been seeing quite a number of the Canon camcorders going to NJ for repairs.To sum, I think this is a racket Canon has devised to rip off customers.So beware when you buy a Canon camcorder, ask the retailer about the tape loading mechanism, and if they have any maintenance plans that will repair it.
