Hi,
I have the West Mountain crimping tool and It works every time.  I started 
out with a $10.00 crimping tool, but the metal connector wouldn't always fit 
in to the plastic shell, but with the West Mountain one, I haven't wasted a 
single connector.
Now, I'm changing the subject a little, but you'll just have to live with 
it!
Another really neat Anderson item is the power junctions sold by
www.powerwerx.com.   Note the spelling of W E R X.  These little units let 
you plug lots of andrson connectors together and they can cary up to 45 amps 
if you use a heavy enough 12 volt ppower cable.
