NewEgg 12 driver anyone?

New Egg is selling a driver for about $18. wondering if anyone has ever tried this product.

It uses a 12 VDC source which would be good for my laser etcher I am building since I will have a 12v source driving everything else already.

Driver/power supply for laser diode/ld 445nm/450nm 1-2w
input voltage: 8-14vdc, 12vdc recommended
ttl: 0-20khz
size: 32*47mm

Just an FYI, that is newegg marketplace, kinda like ebay or amazon, where other sellers have an account at newegg marketplace to sell their own wares.

I don't know anything about that driver.
