I can't fault these screen protectors at all. By carefully fitting them and using a credit card as a squeegee, it fitted with no bubbles or dust.
For those that have problems fitting them, use a piece of sticky tape to lift them once fitted and carefully replace them. If you find dust beneath, lift just enough to gain access to the dust using sticky tape and slide another piece of sticky tape beneath to pick up the dust then using a credit card smooth it back down.
