So with limited options I bought the Orzly effort for £9.99 from Amazon - this time I wont give you the link as this is a cautionary tale.
Having adopted the regular screen install process of having a steamy bathroom for all my other screens I used the same technique for the Orzly. If you don't know what the procedure is a quick re-cap; leave a hot bath or shower running with no extractor fan on if you have one for 15 mins or before the bath is full obviously, take all your clothes off and close the door.Using masking tape line up your screen protector and apply using a left to right technique or if its a glass screen use a small bit of tape as a loose hinge and apply from a top down motion.
Get dressed and rejoice.
So with that done and dusted I noticed there was a mark on the screen in the bottom left like a weird chip under the screen - no idea how that got there so I had to lift the screen - when doing so the Orzly lifted the film that Sony installed already. What the hell ! The glue managed to pull off the film, wow, that's a strong bit of glue, so now the Orzly was completely useless and I was left with a handset with a warranty that's invalid from Sony. Brilliant work Orzly, not to mention no Sony logo on the handset.
My opinion here; Avoid the Orzly Tempered Glass Screen - even for £9.99 its a terrible purchase.
