I haven't used that, but for $1100 you can get a similar laser mounted to the side of an EOTech called the EOLAD from TNVC. .7mW and a good sight to boot. If you can find one and you want more power, there's the Meprolight MOR and it has 5mW red and IR lasers slaved to a 33mm tri-power reflex sight (batteries, tritium and fiber optic) for $1500 (they make a red only but not an IR only and if it has IR it's 5mW because they don't make a .7mW either). It's not a bad sight at all, but it's rare to find one. Altatac had 'em new for $1500 with 4.3MOA dot.
