simple to use, compact and lightweight. Works in tight spaces.
Straightforward to use, just read instructions on package.
Level can be a little tricky to get just right but practice makes perfect.
Easy to read and use on battery banks
I ordered this to use on motorcycle batteries.
Unable to use it because it requires more
electrolyte than is available in these small batteries.
Cleaning instructions are a lttle strange. They recommend use of soapy water to clean the instrument after use. I would be concerned about electrolyte contamination, and use plain tap water with a final distilled water rinse.
