It's only that it has a suspended bit of plastic that actually fits on your head right? To enable the foam to float. There's nothing special in there to enable it to spin, it just floats. I also use a POC spin lid.
I'd say if the foam hasn't taken an actual hit, there's no reason why it's not still fine. Just make sure the plastics are all pushed in and twisted locked into the sockets on the lid and that all your inner foam is velcroed in place. -

Probably a bit wasteful for single use. Every frame will have different angles and tube diameters. You can print off paper templates to wrap around the tubes that do this job fine albeit without the clocking
