Ebay Laser Pointer Scam Exposed
The same scheme is based on the type of light emitted by the laser pointer, the way power is measured, the pointer changes Laser and ignorant and / or dishonest sellers.
Light type
These lasers are advertised as green lasers and should give the green light and green light. How ever not the case. Virtually all supposedly high green laser pointers on eBay power emit a combination of light green with a wavelength of infrared light of light and the wavelength of 532nm 808nm and 1064nm light.
All real high power green laser pointers have a filter that will prevent the emission of infrared light. Laser pointers on eBay are missing these filters have been removed or deliberately manufactured with. To remove the infrared filter from a laser pointer increases its power and makes much more dangerous.
Take a 240 MW laser pointer is commonly found on eBay as an example. This laser pointer is likely to have only 40 mW of green light 200mW with the rest of infrared light being. Customers pay for laser pointers with 240 Nm of green laser pointers with 40mW of light and light. In fact, the deception of 84% of money.
The other problem with the filters need infrared lasers are very dangerous. Infrared light is spreading like a beam of light compared to light green is in a narrow beam. Green visible light that can be avoided, but the infrared light is invisible because you can not avoid. Most safety glasses that protect against Green light is completely transparent to infrared light. This means that a person wearing safety glasses and using one of these lasers is less likely to avoid road much more likely to suffer damage to their eyes.
Power Measurement
The power of laser pointers will peak in the first few seconds, then stabilize at a level much lower than the top. Reputable sellers will give the average power as the Power announced. EBay sellers, moreover maximum power use that power announced. It is very misleading because it misleads people think that the laser is more powerful than it really is.
Changes
These laser pointers are designed exclusively for processing power of 5mW to 10mW world. Vendors change the laser pointers, increasing the battery power of the laser diode so the diode emits a more powerful laser. The problem with that device is not designed to handle the increased power and have a much shorter life cycle and is likely to burn. Many eBay lasers lose power or completely burn in minutes or even hours. The target pointer laser and the acrylic coating are not designed to increase and is likely to damage with reduced performance or fail completely.
These vendors eBay are not laser experts often have little or no understanding of the laser pointers they sell. This means they are unable to provide advice and recommendations and the level of specialist support and services they can provide is minimal. Its global response to customers when there are problems with laser pointers is to send a replacement. Since the cost laser is not much more than the shipping cost, most customers reduce their losses at this time.
Possible Solutions
Laser pointers with powers over 5mW are classified as dangerous goods and are not allowed on eBay. If you've been scammed by one of these vendors, which may threaten eBay to report them and may have their account suspended or even closed.
If you pay with PayPal, you can open a dispute for goods not as described. The dispute may be decided in your favor but most sellers are willing at this time a refund is issued. If you paid with credit card you can start a charge back with your credit card company in a similar way with success more likely PayPal.
The last option is a bluff. Pretend that you contact eBay, police and the ministry responsible for consumer affairs in your country if not issued a refund. Taking into account that are selling an item prohibited by eBay and illegal to sell (legal to possess) in several countries, this cliff is very effective.
