I recently purchased a gadgetshieldz for my iphone from
www.gadgetshieldz.com
The great thing was that they delivered via TNT for free to SA. I was avaling (2 minded) before buying it cause the ZAGG protector got a lot of review on the web and seems to be good but cost like $25. The shield from the gadgetshieldz cost me $7 incl delivery and from the website I could see that the product was similar so I ordered one to try it out.
It came within 5 days, thin little envelope in a huge TNT packet.
The installation was detailed on the web and I was very scared of getting it wrong. I started with the front and it went quite easily using the mixture to get it into place. The back was a bit tricky as I order the full back with the tiny flaps and everything. Next time I would order the flat back instead.
But still it seemed not to want to stick but after a few of letting it dry and trying to stick the corner it eventually held, after a day it was solid onto the phone and after 2 days not most of the tiny bubble dissappeared.

It seems to be much more scratch resistant to the al cheapo screen protectors I normally buy off ebay. I use to replace my ebay screen portector every 3rd week. So far it has been 2 days and no visible scratches. I will update this post if any scratches does appear.
