If you are not selling, trading, or looking to buy anything then this isn't the right section to discuss a DPSS laser.
The wavelength of that laser is 1064 nm
This means that the laser is invisible and very dangerous to the eye. It wouldn't be much use to beginners. Unless you are selling this laser, this thread should have gone in the "Blue, Yellow, & Other Colored Lasers" section of the forum for any discussion.
