I just got one of these and I love it. It's foolproof, easy, high quality, and it doesn't break the bank. If you need to make cables with Anderson Powerpole 15 ,30, or 45A contacts I recommend this Powerwerx $45 crimper.
Designed by Powerwerx to provide a positive crimp for Anderson Power Products 15, 30 & 45 amp contacts in a single tool. The ratcheting mechanism guarantees a complete crimp every time. A built-in contact positioner holds the contact during crimping.
