I've had an AlcoDigital AL7000 breathalyser for well over a year now. It's apparently the most reliable sub-£100 unit you can buy. I use it mostly for morning after testing, and won't drive unless it shows me less than half the legal limit (and preferably zero.)
Just be aware that some people use breathalysers to check whether they are in ketosis - I have done it from time to time. A positive reading (in the absence of any alcohol consumption) = ketosis. Won’t put you in danger of drink driving as it’d show higher than expected, but something to be aware of.
I agree with @DCUKMod on the lows. I’ve only once caught a 2 (2.9) with a finger prick and that was prior to eating something I’d grabbed on the go due to extreme hunger on the way to a meeting. The reading was so low I tested again immediately on another finger on the other hand and the liver was already kicking in as it was 3.2. In these circumstances I find the post prandial rise is much higher than usual, presumably as the liver is helping out.
