questions about the 2 pack driver from o-like.

[TylerHansen]

I am looking to buy this driver for my first build.
2 pack Red laser/808nm laser diode driver 80-500mA w/TTL [OLDD20] - $5.99 : Zen Cart!, The Art of E-commerce
The Ma is fine but im just curious as to why no one ever uses this.

The main drawback is the three week shipping time. It should work for you depending on what you're planning to power it with and the laser diode you'll be using.
