Buyers should be aware that ultimate shield have two versions of this product, one with a cut out for the proximity sensor and one without. I first received the one with a cut out and phoned ultimate shield direct who explained some customers had experienced issues with said sensor, so they were trialling a new pattern. They were happy to send me out the other version though FOC and I received it within a couple of days (I've since posted the first one back to them)
This is the first tempered glass protector I've used but found it very easy to apply and it left no bubbles or smears, it feels nice in use and is a huge improvement on Sonys crappy plastic screen - I applied this directly to the Sony plastic. Been using for around a month now with no issues - cleans easily, hasn't scratched and proximity sensor works perfectly.
