I decided to try a matte finish screen protector rather than a gloss finish because I'm sick of finger marks on the screen so based on high reviews for it's sister product MediaDevil Magicscreen Screen Protector: Crystal Clear (Invisible) - Samsung Galaxy S4 / SIV (2 x Screen Protectors)
I thought I'd give this one a go.
The prompt delivery from the supplier cannot be faulted. I ordered late on a Friday before a Bank Holiday with the free delivery option (expecting 5 working days turn around) and it arrived on the Tuesday, effectively the NEXT full working day. That kind of service cannot be grumbled at!
Straight out of the package I found a similar set up to what I've had with cheaper screen protectors for previous phones. Two thin plastic screen protectors, a cloth and card applicator system. It normally takes be a good couple of tries at getting these applied perfectly and as I was doing it while I was supposed to be working it made the job that much harder. Basically after cleaning the screen with the cloth you peel back part of the cover labelled "1" and apply from the top of the screen downwards peeling back the cover and applying pressure with the card applicator at the same time. It can be tricky to prevent bubbles, especially in a dusty environment and I failed twice as there was too much paper dust in the office air which immediately stuck to the underside of screen protector. Following instructions on how to remove the dust from this side I saved the screen protector using sticky tape to remove the dust and applied again. It was third time lucky as it stick down with zero bubbles.
Once the screen protector is on you then peel back another cover marked "2" to reveal the matte finish. The quality of the matte finish is very good, giving the screen an almost paper-like look and while the glare is not completely blocked out it certainly does a much better job of it than gloss finish screen protectors do. As for leaving fingerprints and marks on the screen the matte coat doesn't eliminate these completely, especially with damp, greasy or sweaty hands but it is a big improvement over the gloss.
Protection is so far pretty good and light scratches and marks buff right out though I have not yet subjected it to much harsher treatment. I dare say if you work in an environment with lots of grit and debris you may need to look for a more hardcore screen protector but they will cost a great deal more.
So to summarize it's a great quality product (remember you get two of them in the pack) and fairly priced considering the competition. It can be just as tricky to apply perfectly as any other screen protector using the cloth/card application system which is the only reason it escapes a 5 star review. Harsh? Maybe but there will be people who are even more clumsy than me who'll be all thumbs trying to get this applied.
