I've been running a LabRadar for a few years. I have had no problems once I figured everything out. There is a short learning curve when first starting. I shoot plenty of .224 bullets with boattails and they all get recorded. None of my stuff shoots at the 4,000 fps limit, so no problem there either. I bought an inertia trigger because it was highly recommended. I never use it because it just wasn't needed with my set-up. I use a LabRadar battery pack and no memory card. I mount the unit on a tripod and place it directly in front of me (off the bench) where I can easily reach the buttons from my shooting position. Get a hard case from Harbor Freight and the unit will never get damaged.

I highly recommend the LabRadr, it's one of the best investments I've made.
