I bought a cheap one to adjust the hammer spring instead of setting up the labradar every time. And I can shoot into a box on my back porch. It's just more convenient to have something like the Chinese thing. I tested it against the Labradar to see if its worth the time. I think it does an adajit job. I know others don't have to money to invest in high dollar chronographs, I don't. I just have access to a Labradar, I don't own it.
Are you going to get exactly what the speeds are? No.
Can you tune your rifle using one? Yes
I think it is very useful and saves me time.
I don't shoot groups with mine on, I'm just looking at the numbers. Others use a tripod and don't attach it to the rifle.
It cost less when I bought it, you can find them for 15 bucks. This is just a link to the one I own.
