They do not protect against lightning strikes, and because they use MOVs, the protection is sacrificial.
I have a couple of Furman units. One has been trouble-free for 12+ years. In the other (a PST-6), the "Protected" light stopped working after about seven months, which supposedly means it can no longer protect against surges.
Because we live in an area with a lot of surges caused by the power company, I have switched to using three series-mode Zero Surge units on all my expensive stuff. All three of those have been genuinely trouble-free.
