Best bit of kit I purchased. Australia to UK in 9 days. Very easy to use, repeatable and accurate readings. Sorted my idleing and throttle response issues saving me having to use a mechanic.
I finally received the Lambdaking Mk11 after a mess up by Aust Post. Raytech despatched the unit very promptly, and then Ray went out of his way to find what Aust Post had done with it - All resolved. Thank you Ray!
Used the unit on some of our classic cars and it works a real treat - very easy to use and understand. Can strongly recommend this unit!
