Wanted to add I ordered a set of the Xtremeguard protectors from ebay after reading about them in this thread. Shipped very fast, 3 days from utah to vermont.
Initial impressions / mini-review:
They apply quite differently to the Bodyguardz/Zagg. I found them to be less tacky and more slippery once water was applied. Good for repositioning but took me by surprise when I started to smooth it on and the whole piece slid right off the end of the phone!
I have found the Bodyguardz to be just tacky enough to slightly wiggle in to place and then they start to adhere.
Cut is fairly good but not as accurate as Bodyguardz. The coverage is actually so 'edge to edge' that I can actually feel the skin edge on the back of the phone where it's almost overlapping the sides, which I can already tell is going to piss me off as I'm catching it with my hand. The Bodyguardz skins are all cut just a tiny bit smaller than the area you are covering so you don't run in to this.
Also, the pieces intended to cover the sides of the phone were a joke, not even close to the right shape or size. The cut also hadn't quite cleanly separated the skin template from the surrounding material so there were a couple of places I had tiny 'skin tags'.
They've only been on for a few hours so can't really comment on the finished product yet but initial impressions are good. I'm hopeful for a crystal clear and smooth finish once fully cured. I certainly didn't have any problems with bubbles, they went on nice and smooth and were very easy to squeegee the water and bubbles out of.
Overall:
For the price, these are a bargain. If you are OK with getting great value for money at the slight cost of a not quite perfect product then you can't go wrong with these. I'll be very interested to see how these stack up against the Bodyguardz when fully cured in terms of clarity, feel and longevity.
My 2c.
