Works good!
Well i've read reviews about not being accurate but i think alot of people forget about voltage drop if not connected rite to the battery. MIne was test at battery and was the same as battey, then connected inside camper for being able to see voltage....and again was same as what i tested inside the camper as per load being used.

Works fine, not too hard to see in sun
At extreme angles it can be tough but reading it straight on with sun shining on it isn’t too bad, doesn’t require having to shield it with your hand. I’m subjecting it to saltwater on a kayak so who knows how long it will last but is probably the most readable of the the Amazon choices.

Not at all accurate
This thing is j-u-n-k junk. Reading isn't even close, either in charge or discharge. Charger says 40% meter says 100%. Battery charged for another 3 1/2 hours before charger indicated full. Move on from here and get yourself a quality meter, I don't know where that's at but don't buy this thing.

size
I liked the fact that it was small so that I could easily put it in my tackle box. Also that it shows a % charged, not just some lights that come on, it seems to work fine.
