Can someone please recommend me decent P plates?

[ILLaViTaR]

Hey guys as the title suggests I've had it with all these different types of P plates.

I first of all tried the rubber ones (That stick on the outside).
Those fell off in 10 minutes (Clean surface).

I then tried the see through so called reusable ones (That most use).
Once removed they are not reusable, they just curl up (I tried boiling them and didn't fix it).

I then bought some suction cap ones, they've so far been the best but they are still falling down.
I cannot tape them up because my parents use the car on occasions.

And yes the Windows are clean lol, The rear window even stays down a tad to avoid a temperature shock but still they fall.

Without removal the see through are by far the best however I need to detach and reattach.

Any suggestions?

Thanks.
