As a professional driver, losing my licence is not an option for me. So I thought it would be sensible to invest in a alcohol tester. I love the compact size of this Kenwood tester, and that you can simply blow into it and get an instant reading. If it saves my licence it will have more than paid for its cost, my wife is using it too!
Good set which includes batteries and a clever twin strap to keep the straw attachment handy. You don't need to use straws with this (you can use a drinking straw) just blow across the top. So simple to use, one button. Gives consistent results quickly. Ready to go out the box doesn't need any calibration or complicated setup like some do. Feels very high quality.
