I just ordered one and will give it a try. Have been waiting for the Lab Radar unit but they are obviously having a few challenges getting started so I will wait and let them get everything worked out before investing in that. I have heard that some folks are concerned about hanging 4.4 oz on the end of their barrel and the effect that will have on accuracy. I also ordered the rail adapter so I can rig something up to take that out of the picture. I'll be using it on an AX and Coyote so with minor fabrication I should be able to attach it to the forend rail. I wonder if it will work off the side? Can't see what would make a difference but stranger things have happened.
The adapter makes it usable on pistols as well.
