Review on 2-Pack HYB Slim Digital HID Ballast 55W 12V - Universal Fit For H11, H7, H8, H9, H4 & More! by Darren Munajj

Had these for 11 months and thought I had a problem with one and customer service was great. Responded almost instantly several times over a couple week span. And sent replacements. The problem ended up being the wiring so I thought I could at least give them a good honest review. And I have had several sets of these on different vehicles over the last couple years with no issues.
