Good so far

Only have had it installed for about a month, the only thing so far that I would like to see changed is more mounting holes, that way you have more options in tight places like I had to mount it.

BEST CHARGER IVE EVER OWNED

This charger is an absolute BEAST!! By far the best 4 bank charger I've ever owned. I've been running it for about 6-8 months and its performed flawlessly!! Guys If you're not familiar with what I do, check out my socials and you'll see me put everything I own to hard work! I am rough on my stuff! I buy it to use it and I don't care about a scratch, ding, or dent. I put my boat and all my equipment through the ringer every time I go out. WattCycle makes QUALITY products at an incredibly low price! https://www.facebook.com/JoelDavisFishing
