In theory, yes, under certain circumstances. In reality, are you willing to risk it for a few sats or bucks? We stand behind our product and hence using 2nd hand Trezor in terms of hardware durability shouldn’t be any problem. Trezor should remain operable for many years.
But in terms of opsec and your privacy or security, 2nd hand Trezor may embody a risk of men in a middle attack (someone replacing the genuine piece with malicious fake) and hence it’s not worth the risk.
Everyone loves to save a buck so if this is your concern, subscribe to our newsletter or check this forum regularly to see if there is some promo action going on
