Better than the version with central, locking lever

This arm is just Magic as Manfrotto says. You can easy attach whatever you want and nail the position. It can handle heavy stuff like a big dslr with proper glass. I also have the other version with a lever instead (143N) of the knob. That one can slip/glide and the lever can become hard to manoeuvre in some positions. I recommend you get this one instead.
