When searching “laser
pointer shops” in google, there are 3,660,000 results appears.
Consumers got lost in so many laser pointer suppliers, they check some top
websites, visit their products there with product descriptions and photos then
compare price or sales quantity then place order directly. But do you know
there are many unqualified laser pointers, potential damages would occur once
you operate them.
A recent study released by
researchers at the National Institute of Standards and Technology (NIST) has
revealed an alarming trend. Of 122 laser pointers tested, 44% of red laser pointers and
90% of green laser pointers tested failed federal safety regulations.
The
primary danger is overpowered units. Some units in the NIST study tested as
high as 13 times over it shows in label. As what we know, the higher the power
is, the more expensive the price is. Instead those laser pointers provided by
some suppliers even in a much lower price. Accordingly to research, the extra
power comes from infrared reflection, which is invisible to human’s eyes but
full of harm. Consumers would well consider the safety when buying a high power
laser pointer, while buying such gadget would bring direct danger without
notice.
It is common consumers are always attracted by lower price, one can never knows product quality by seeing product description only.In order to gain much more benefits, some black-hearted
suppliers use second-handed laser diodes inside, which do make the price competitive,
but also lessen laser pointer’s lifetime. Usually, a good laser pointer can
work more than 8,000 hours in total, while a used diode laser pointer only an work
hundreds of hours time as they already being used for a long period. What’s more, it is fact that unqualified laser pointers' body material, IR filter, cooling system
maybe in bad quality. Price need to be considered, but should not be the first
one.
Finally,
after-sale service need to be offered if needed. Consumers pay money not only
for product itself, but also for good service, especially after-sale service.
Reliable supplier can provide helpful support within guarantee time once there is any problem of laser pointer, while non-reputable laser pointer company would find many
reasons to refuse consumers maintenance or even ask for much repairment
fees.
