Don't buy one of these
Broke down after 4 days. Replaced battery but operated for about 2 tests and nothing after.
Ended up throwing it out as I guess you get what you pay for.....
I wouldn't advise buying this at all...
Purchased another brand from another store. Working well so far.

Works perfectly
Did a little science experiment to test the accuracy. Measured all drinks and timed between each test. Was very accurate.
