Not very good - FAB Defense SPIKE Tactical Bipod

I bought one of these and returned it. I can't believe all of the 5-star reviews. The one I received was rickety and rattling. The center lock screw was difficult to tighten, and it would constantly come loose. I have a cheap $20 bipod I was using before I bought this, and it is almost as stable and it's easier to adjust. I'm not comparing it to the Atlas and Accutac. They are better and more expensive but not that much more expensive than the FAB. I returned this one and bought an Accutac WB-5 on sale on sale at DVOR.
