You don't have to see the level, it shuts off and doesn't over fill. Have used it twice now and am happy with it.

Those work great. However, I have the battery cables (4 house batteries) crossing over the caps and a bundle of heavy gauge wire crossing over the rearmost caps. I can't even get the caps off, much less use the filler!
