Nice, compact, intuitive, easy to use & store
So far, so good. It confirmed the good state of a good battery in a 1 year old car and recommended to replace a 7 year old battery and confirmed the bad state of another battery that had been used as a backup for a UPS. I hae not used it to check start the car diagnosis or alternator functioning. It replaces a bulky tester that put a huge load on the battery and did not give anywhere near reliable results. I like that it is compact and fits into a drawer readily.
The manual is a bit vague, and the English is is not the best. As manuals and tools can be readily separated, it would have been nice if abbreviated instruction could be on the instrument or a "tag" on a cable which is a common practice for many household small appliances. Timely shipment, packaging was adequate.
