Just got a new Nexus 5 and needed a screen protector. I've used others in the past with varying results so thought I'd give this one a go as I was impressed with the thought that had gone into the process of fitting the protector and the very informative YouTube video.
It arrived in good time and well before the estimate - a good start. The kit contains enough stuff for 2 protectors including 4 hinge stickers, 4 dust removal stickers, a nice, stiff smoothing card and a lint-free cloth. Considering the price, I was really impressed.
Fitting the protector was really easy and with the aid of the positioning stickers, I got it right first time. The film almost smooths itself and there was hardly and smoothing to be done - just a couple of small bubbles in the corner.
Once on, the protector is practically invisible because the shape and the cut-outs match the phone perfectly.
I went for the anti-reflection version and it does seem to work well. Obviously, there is a slight loss of contrast in the screen image but that's to be expected and the trade-off is that it's clearer in situations where there are bright lights.
It seems to be scratch-resistant. I've only had it just over a week so difficult to tell how it will perform over time but, of course, I still have another one should the first need replacement.
Overall I'm pretty impressed with this.
