6th AlcoHAWK Micro
Best Price: 19.99 (bargainbreathalysers.com)
Sensor: Semi-conductive oxide
For: Tiny; decent accuracy; price
Against: A little confusing to use
The Micro did a reasonable job given its budget price. However, it started to struggle a little during the tougher tests.
Value for Money:
Cheap to buy and looks it.
Ease of Use:
The Micro is true to its name; its incredibly small no bigger than a key fob. The on-screen instructions are limited to a flashing red LED, which is not particularly intuitive and it can be confusing as to what the device is doing. However, results are displayed immediately and clearly after a test, and its easy to set up.
Calibration is needed every 12 months, which costs 12.95 for full service and calibration if paid at the time of purchase. Normal price is 22. The Micro comes with a protective leather pouch.
