Ebay Laser Pointer Scam Exposed
The same scheme is based on the type of light emitted by the laser pointer, a form of energy is measured, changes the laser pointer and ignorant and / or dishonest sellers.
Light type
These lasers are advertised as green lasers and should give the green light and only green light. That how ever is not the case. Virtually all supposedly high power green laser pointers on ebay emit a combination of light green with a length wavelength of 532 nm light and infrared light with wavelengths of 808nm and the light 1064.
All real high power green laser pointers have a filter that prevents them from issuing infrared light. The laser pointers on eBay are missing these filters have been removed or deliberately manufactured with out. Removing the infrared filter from a laser pointer increase their power and makes it much more dangerous.
Take a 240 MW laser pointer are commonly found on eBay as an example. This laser pointer is likely to only 40mW of green light with the rest of 200mW of infrared light that is. Customers pay for laser pointers with 240Nm of green light and only get laser pointers with 40mW of light. Misleading effect of 84% of your money.
The other problem with missing the laser is infrared filters are very dangerous. Infrared light is spreading like a a torch beam compared to green light is on a narrow beam. Green visible light that can be avoided, but the infrared light is invisible because it can not be avoided. Most safety glasses that protect against green light are completely transparent to infrared light. This means that a person wearing safety glasses and using one of these lasers are less likely to avoid the beam, and more likely to suffer damage to their eyes.
Power Measurement
The power of the majority of laser pointers will peak in the first few seconds then stabilize at a level much lower than the peak. Reputable sellers will give the average power as the power of advertising. Ebay sellers instead use the peak power as the power rating. This is very misleading because it confuses people to think that the laser is much more powerful than it really is.
Modifications
These laser pointers are only designed to handle all the powers of 5mW to 10mW. Vendors change the laser pointers, increasing the battery power to the diode laser diode laser emits more powerful. The problem with that the diode is not built to handle the higher power and have a life cycle much shorter and is likely to burn. Many ebay lasers lose power or burn completely within minutes or even hours. The goal in laser pointer acrylic coatings are also not designed for increased power and is likely that damaged with reduced performance or fail completely.
These eBay sellers are not laser experts and generally have little or no understanding of pointers sell laser. This means they are not capable of giving expert advice or recommendations and the level of support and service we can provide is minimal. His general response customers when there are problems with laser pointers is to ship it back for a replacement. Given that the cost of the laser is not much more than the cost of shipping, most customers reduce their losses at that point.
Possible Solutions
Laser pointers with powers over 5mW are classified as goods dangerous and not allowed on eBay. If you've been scammed by one of these vendors, which may threaten to report them to eBay and may have their account suspended or closed, even.
If you pay with PayPal, you can open a dispute for goods not as described. The controversy can not be decided in his favor, but most of sellers are willing at this stage, a refund is issued. If you paid by credit card, you can start a chargeback with your credit card credit in a similar manner with a greater likelihood of success of PayPal.
The last option is a bluff. Claim will contact eBay, police and the government department responsible for consumer affairs in their country if they do not issue a refund. Considering they are selling a prohibited eBay and illegal to sell (legal to possess) in several countries, this bluff is very effective.
