I bought a spare for each of my N900s in case I trashed the first ones putting them on, but they went on so perfectly, no dust or bubbles that I now have two spares that I don't anticipate using.

Fitting instructions:
Wash your hands
Wash the phone screen (including the greasy edge bits)
(I chose to) Peel about 2 inches off the backing at the camera-eye end
Butt it up flush with the metal rim round the screen
Rest a finger on the top of the protector
Peel the backing away smoothly, following pressing gently with your finger on top of the protector
The adhesive layer on the protector is attracted to the screen easily
I didnt even need to squeegee any bubbles out, just pressed the edges down
Took a few minutes, photo available of the finished result on request

It has cutouts for the camera, earpiece, nokia logo and prox sensor and fits with half a mm or less gap all the way round. Touch screen feels like before (no papery texture like the ARMR200) and isn't noticeably less sensitive. Overall finish resembles the standard screen

£5 in my paypal account gets it posted to you first class UK royal mail. I've got some spare alcochol wipes you can clean the screen with, just ask in the PM

First come, first served (by order of public thread posting) - please say here that you'll have one and PM me your details. I'll advise the paypal account info via PM

Cheers
