    Looks and feels rather professional - did not test it against a device the police uses - so I can not say how accurate it really is but it appears to work quite reliable ... A downsize is the manual is in Chinese only no english manual will be delivered with it.

    everything came as it should, I work perfectly, pity there is no memory memory, or how to insert a memory card, (to remember and how much was before.)😄😄😄😄😄

    Very useful tool for all drivers I can only recommend it because we can make sure that there is no alcohol left in us and we can go on our way pleasantly small and very reliable!!
