Default it will be pity if 1w blue laser pointer has no focusing function

How to say,,, if there is no focusing function, the power of 1w blue laser pointer will be wasted, so it will be very pity. Currently, there is a focus lamp which comes from Taiwan, the price is almost 10 USD/PC. As for the effect after focusing, the focus can be 1 M beyond. As we know, even if 532nm or 650nm can carry out focusing , its focus is very short, only one decimeter. Especially in China, people set off the firecrackers during Chinese New Year. This product is very suitable for this condition. You can ignite the lead wire when you are 1 m away, it is really great. It can burn through the wood, newspaper, and CD box through focusing.

If you are stating information on a product... it is always a good idea
to post Pictures or links to Pictures of what you are talking about..

Thanks Firefly. These are numerous in my tool box already from both those reputable vendors. This seemed to me to be a supplier that may distribute to those types of sellers you mention so am curious as to what they may be able to offer the forum and what they know about a product they appear keen to promote.

Of course they may not be selling it at all and simply offering us some advice they feel we may be missing. For that too, I thank them for their efforts.
