I have CLEAR and have only ever used it once. It’s free to me, so I keep it active, but I really don’t care all that much for the product. I find that TSA Pre Check is perfect for my needs and the airports I frequent. I seldom wait more than five minutes to reach the TSA agent, though I know some people (my partner being one) have been faced with situations where not having CLEAR would have meant missing a flight due to unexpected crazy lines because of TSA dealing with staff shortages.
