I am a sucker for good reviews and the alcosafe certainly has a few. I don't drink an awful lot but do enjoy a few glasses of wine at the weekend. A good friend of mine recently lost her licence having been breath tested on her way to work. She had been at a party until the wee hours but thought she would be okay to drive - WRONG !
This frightened me and so as peace of mind I thought I would invest in a decently priced breath tester.
I am very content with my purchase, seems to be reasonably accurate and I feel comfortable using it, As has been said many times, the traffic light system works a treat - no green light - ditch the keys !
The only minor criticism was that it arrived promptly but with a slightly crushed box, inside was all well thankfully.
