Good for getting a rough reading

Overall, this tool will do a good job of letting you know whether any of your cells are bad. If that's all you need to know, then it's is a fine product.
I found, however, that the readings are not consistent enough to provide accurate measurements. Test after test usually ranges plus or minus a graduation (about .025 each).
Previously, I had a complaint that it was difficult to tell if the proper amount of fluid was being used because the meniscus (curvature of the liquid) didn't match with the fill-to line, but was informed that standard practice is to read at the bottom of the meniscus. I may have known that at some point, but certainly forgot about it. So, it turns out I've been using a number of devices incorrectly, but unfortunately with this one the readings are still inconsistent. Regardless, I've found this item to be useful enough that I'll give it a star boost.
