Product came as described. Install was easy. Battery came 100% charged. No vibration tape included, that was the only drawback.

Westinghouse has junk batteries in their generators and I had to buy a new one and prove to them that the battery passed a load test before they would replace the starter in the generator that was bad as well. So far very happy with the Mighty max
