Bests & Worsts Reviews from Amazon

I paid almost $120.00 for this and it failed before I ever got to use it. I had it 2 years, kept it fully charged, but when I needed it, it didn't have enough power to even turn the engine over. The factory says it will rrepair or replace it, but they want another $85.00 to do that, and you have to ship the broken one back to the, which means a big shipping charge: this is essentially a battery, and batteries are very heavy - and costly - to ship. Thumbs down on this loser product.
