"I ordered this kit on 'deal of the day' and picked it up from my local Branch. When opened I found the breathalyzers expired the previous month. If stopped the french police are hot on this so you should check and buy an 'in date' kit if required. Whilst Screwfix offered to take the whole kit back and refund the money, a new Breathalyzer pack bought locally is only half the discount so it was still cheaper to keep the kit. The rest of the kit is fine and has a nice bag to keep all the items safely in."
