They're easy to use and show you your alcohol level within 2 minutes.

    Rated 1 out of 5 by from It's set to non-UK limit I didn't find this as helpful as I hoped and that quite simply because it only detects if you're above the French limits for drinking and driving, which are considerably lower than the UK limits. I wanted it because I wanted to confirm when the alcohol in system had reduced sufficiently to mean I was ok to drive -and so not stay my journey until then. Although there are rules of thumb, they are very imprecise and unreliable, so I wanted to gain some certainty. Because of the lower limit tested for (UK is 0.8, France is 0.5), I suspect that I ended up waiting quite a lot longer than I needed to. Because it's a straight pass or fail, there's no way of being sure, which mostly defeats the object. Ok, I accept that it's erring on the side of safety, which I'd obviously better than the opposite, but I really think it would be good if Halfords offered one that reflects the UK limits given that these are being sold in UK stores. Also, as these are one-use and only two in a pack, if you still haven't passed by the time you use the serving, there's no way of knowing when you do in fact fall below three limit. They work out quite recurrence on that basis. I have since purchased an electronic unit that I can re-use as much as I wish, and which gives a digital read our of the actual level measured, which means it's suitable for any country printing you look up what the limit in that country is. So I'm able to keep free-testing untill I know I am bellow the 0.8. If I do wish a margin for error/safety, I can choose that myself rather than have that forced on me because the tester is aimed at a different country. The electronic until was only only just over twice the price of this, so already given me pay back as against the cost of these in just a couple of weeks, plus, with interchangeable mouthpieces, it can be used by multiple people. I would definitely advise not buying these if you can possibly help it unless you just need something too urgently to get an alternative, and accept that it will at least err on the side of caution.

    Rated 4 out of 5 by from Not suitable for new drivers These measure to 0.05% but new drivers (less than 3 years) now have to be within 0.02% in France. Please be aware!

    Rated 4 out of 5 by from Cheapest option to comply with French laws Bought these to keep on the right side of the law while driving in France, don't plan on needing them but..... They are only ones that comply with french NF standards other than a digital one which cost well over £100

    Rated 5 out of 5 by from Just to show! This product is easy to use and brought to prove a point to my daughter who said she would be ok to drive at 4pm when she had been out until 4am. Guess mum was right after all. Needless to say I dropped her off!

Some of the parts we sell here at Halfords have been reconditioned. These will carry a Refundable Deposit or an extra surcharge amount. When you add one of these reconditioned items to your basket, we'll add this extra cost automatically.

Once you've sent us your old item we'll check it over, and then refund you the full surcharge as long as everything is ok.

Before you return your old unit please make sure it's in re-serviceable condition. So if you're returning caliper casings, you'll need to double check they aren't badly damaged or broken. If the part you've sent is found to be unserviceable, we reserve the right not to refund the surcharge.
