hi , we didn't know who the video belongs to, and didn't notice any copyright claim in it. If I found it on the youtube , I wouldn't upload it once again on the youtube , no one will do that . We didn't want to offend you , if this behavior hurt you , I'm very sorry.
No, we make laser pointers ourselves . Who is dx ? Better quality and higher price. Some members don't need to criticize me again and again. We're serious seller. Pls don't tell tales about our products.
