Is very good and good price.

I would recommend this product. It busted my system by 1/12 volts. It hits much harder, but the problem is that sometimes it get loose on the battery it self. But still a great buy.

This is a nice looking clamp and I'm generally happy with it, but it could be improved.

Pros:
-Nice looking--cleaner overall appearance
-Display works well--lights up RED, turns off after a minute without voltage change to not drain the battery
-Covers post completely--may keep it cleaner/more protected from rust, etc.
-Probably better electrical transfer with set screw inputs rather than ring terminals, and silver plating
-Plating seems durable--when trying to find a way to clamp a jumper cable to it, the teeth didn't seem to mar the finish too much.

Cons:
-No place for a jumper cable or battery tester to clamp onto
-Limited inputs--if you have more than four wires, or your wires don't happen to be exactly 0, 4, or 8 gauge you will need to buy a distribution block. Could be vastly improved by having a screw to accept rings terminals for extra/different gauge wires.
-Display is nice but in practice an interior gauge or data logger is more helpful, and the space it takes up on the clamp could have been used to add a ring terminal input or make it smaller.
-Large--hangs off battery
-Allen keys--may be more annoying for some to remove clamp than ratchet. Also it would have been simpler to only use one size key rather than three. Would probably have been easier to have the set screws on top rather than bottom, but would have detracted from appearance.
-Hard to get wires into set screw inputs--Even with the possible benefit of better electrical transfer in comparison to ring terminals, it is almost impossible to get the wire in without many of the strands not making it into the hole.

Good clamp. It can be improved if it has 2 0awg output.
