Review on ZOOKOTO 12V-24V DC 10A Car Audio Inline Circuit Breaker: Superior Stereo Switch System Protection and Inverter Fuse Holder by Jacob Andreti

I bought three of these 20A circuit breakers. I installed all three in my converted van but I only have one working circuit at the moment. The first block I had in a working circuit didn't work so I had to replace it with one of the other blocks and it works. What was wrong with the failed unit was that it stayed in the off position. I couldn't reset it. I haven't tested the third block in the chain yet, so I'm not sure if it works. I was able to return a failed unit to Revain with no problems other than repackaging and shipping. I read reviews from other customers who had similar issues with it. The quality isn't the best, but for the price I took a chance. I haven't decided yet if I would recommend them to others.
