I, too, have a Craftsman "click" type torque wrench that I have used successfully for almost 40 years. Some things that are necessary for a long and accurate life:
1) Be certain to reset the torque value to zero before returning the unit to storage.
2) Do not bang or jar the unit in any way.
3) Never use a torque wrench to loosen any fastener.
That being said, I have no idea about the quality of the current Craftsman product and would be somewhat hesitant about purchasing same given the huge decrease in quality suffered by all Craftsman tools over the past 15-20 years. Compare brands carefully prior to purchase.
