There good one had a small dent in it

Perfect Condition!

Although this ultracap is b-stock and cost considerably less than a perfect unit it was mint. One sticker had a scratch and can't find anything else wrong with it. Thanks, Big Jeff!

I had no issues and love the product

Fixed my voltage drop

Fixed my voltage drop was dropping below 11.5 with one keeps it above 12 and two keeps it above 13

It’s awesome thanks


Works perfectly. Enjoy having the voltage read out. Seems to be pretty accurate.

Great amp

This little amp is pretty impressive for the size. Mine has been going strong for 2 years now through extreme heat and cold doesn't skip a beat.

Great stuff thanks big jeff
