Extremely Useful & Good Value.
Extremely useful battery tester (even tests button batteries) and well-priced, so good value. I kept pressing the two silver 'buttons' (top right) expecting them to 'do' something, before realising the are two touch terminals for testing 9v batteries!! (Various voltages are shown on the tester but are rather tiny for old eyes!). Excellent!
