I don't have one but will offer a few opinions. I think it can alter POI so you can't sight in or shoot groups with it mounted. Also, if trying to chronograph multiple guns, it is a PITA to switch between rifles.

The good is they are accurate and are not affected by direct sunlight like traditional screen chronographs. I have a prochrono and a shooting chrony and both will go crazy when bright sunlight hits the screens.

Another option is a Labradar. They are expensive, over $500, but I have read good reviews. Easy to set up, not affected by light and will not affect POI. If you do a lot of shooting it may be worth it.
