I really liked this simple, effective device until the battery charge tester/calibrator fell out of its case. This prompted me to examine it to see what went wrong. After doing this I discovered how weak it was in place. Obviously with a small drop of glue to attach the plastic pin to the lid. I'll tape it back, of course, but for a company that specializes in complex test equipment, it seems like they could test this device a little more before sending it into the field. The electronic sophistication is great, but check out the nuts and bolts too.
