Caution with laser pointer, shoddy laser pointer should be avoided

It is never fresh that a lot of people have got the familiar experience of shoddy gadget. So the laser pointer is. I have come across a lot of customers complaining that they have got shoddy laser pointer. It is really a quite unfortunate thing for consumers on such condition. People will be not just feeling angry with such gadgets, while the most serious thing would be that it is quite dangerous for consumers once holding such shoddy lasers without aware for a long time. As a result, it is never too much for consumers to take extreme care while selecting a laser pointer.
With the constant improvement of laser crystal manufacturing technology, a large variety of laser pointers with various kinds of colors and output power have flooded into the market. Meanwhile, the competitive market has forced suppliers to reduce the price so as to earn the market share. It is a pity that large quantities of shoddy lasers are also flowing into market with attractive price. How to identify genuine lasers from those of shoddy ones is quite important during their selection.

The low price has made some of manufactures to produce low standard and low specification lasers pointers so as to meet the need of low cost. As a result, a large quantity of shoddy laser pointers have flown into market. Usually a laser pointer includes diode, crystal, les assembly, IR filter, shell, heat sink, circuit board, battery, battery charge, and fine designed suitcase. However, a shoddy laser would not have infrared light filter at all, which is quite dangerous to hold in hands. Besides, shoddy lasers are usually designed and manufactured at the lowest standard to meet the lowest specifications. As a result, it is impossible for a shoddy laser pointer to keep a long lifetime, and it might burn out within a week time. Comparing with genuine Acheron series pen style green laser pointer which owns a long lifespan of more than 8000 hours, it is really not worth at all to choose a shoddy laser.
