Don't buy a cheap one, unless your really feeling lucky that day I have several early 1/2 inch drive beam types, a 1/2 inch drive Proto clicker, a newer Snap On 1/2 inch clicker that failed early last year, Several inch lbs wrenches, a small Proto 3/8 drive clicker that goes up to 150 inc lbs, another better brand 3/8 drive clicker that goes up to 700 inch lbs and a Proto 1/4 drive beam type 0 to 150 inch lbs for checking rotational torque when setting up rear ends for bearing preload.
I should compare my clicker Snap On to the Proto clicker to see how close they are now that I had to pay to have the Snap On calibrated after the repairs to fx it and then compare both of my 1/2 inch beam types to see if there close to the clickers or not
