Did you read the one-star reviews? I always read the one-star reviews on Amazon, often for products I have no intention of buying. The entertainment value alone is priceless.
Of course.
I also write reviews. Reviews are very important for online shopping.
1.0 out of 5 stars Unit self-destructed on first use!, December 8, 2010
By phil1701 (Tucson, AZ USA) - See all my reviews
Amazon Verified Purchase(What's this?)
This review is from: Metro Vacuum ED500 DataVac 500-Watt 0.75-HP Electric Duster 120-Volt (Tools & Home Improvement)
Unpacked unit upon receiving it, wanting to test it out before using it on any devices. Upon plugging the unit in and turning it on, the device began emitting smoke instead of compressed air. Unit then began to emit flame before I could unplug it. Certainly not how I was expecting this duster to behave.
Sounds awesome. It is a win-win situation. If it works, it is good. It it becomes a flamethrower, that appeals too.
Hmmm. It seems other folks had problems with smoke too. Pity, hope you have better luck.

Anti-smoking fanatics always complain a lot.
No seriously, I'd love to see your opinion after you use it. I might be interested.
Of course. I'd be happy to share my thoughts.
For Amazon reviews, it is important to be able to judge the review. Most of the time, a review falls into one of these categories:
* Judging the expectations of the buyer, not the actual product (usually involves not reading descriptions)
* Judging the seller, not the product
* Judging the product
Most people are inclined to express negative opinions rather than positive, so bad reviews are always prominent, as they should be.
This item has 446 reviews with a 4.5 star average. So, negative reviews are good in that they show somebody is not falsifying reviews, and it shows that one can get faulty units. Every product I have ever ordered which had several negative reviews with horrible experiences which were the result of defects like that turned out alright.
I am more concerned with the nozzle being shot off actually. They updated this product to make it latch, so I hope I do not get one of the older units.
But an airgun is cool too.
