    Can be a 5 star product with a software update.

    Needs some polishing to be a 5-star product. Good news is most of the issues are software based, so an update could solve all of them:

    Needs ability to perform a storage charge.

    Battery icon that shows charging/discharging state can be a bit hard to read, especially when battery is near full or empty when there are only two frames of animation playing. Either the battery icon needs to change color when discharging, or battery animation needs more frames to determine if the battery icon is 'filling up' or 'draining'.

    Charging complete state could also be a bit clearer, it took a while to figure out that no animation = done.

    No information to view or ability to select NiMH battery charge method.

    It would be nice to view the internal resistance of the battery in the slot (even if it is a 2 wire test). (although it does come with kelvin probes to do a proper 4 wire test)

    Charging current should be more than just 4 options.

    There should be a way to fine tune trickle charging.

    There should be an option to loop the capacity test and display the values for all runs.

    No way to turn off screen.

    Fan can be very annoying with a tinny noise, but that is a nitpick.

    Picked this up to replace an xtar VP4 plus that's given me nothing but issues. The Epoch has all of the functionality I'm looking for in a charger and is very user friendly. A bit pricey but worth the money in my opinion.

    This charger is absolutely awesome. Everything worked right out of the box and as advertised. The touch screen is responsive, the diagnostics are great, and it takes care of my 18650s and 28650s. I have yet to try it on NiCad batteries though. We'll see on that.

    Yeah, it is expensive; but, I am not sorry that I bought it. It was well worth the $99.00 !

    I world definitely recommend this to anyone looking for a top notch charger.
