I just installed my white stone dome glass. Yes it is expensive. But I paid $39 for the PureGear one at the T-Mobile store and was pretty much let down with it by the time I got home with it put on at the store. In a month the pure gear was coming up, dirt start to get under it cus I wasn't full adhesive and not tight to the phone all the way around.
The white stone dome feels like the naked phone glass with no matrix dots, it's so clear.
I hate spending too much money and the PureGear was pure garbage. I should have never got it. What I would suggest is don't pay full price for the the white stone dome. I got mine on the post labor day sale 30% off, $31.50 they seem to be having sales often for 20-40% different models all the time. My suggestion is watch and wait for a deal like that and jump on it.
The installation looks super complicated but it's not if you watch some YouTube videos on it and read the instructions. Important tips - make sure the table or work area is as level as possible, this is most important. The area should be clean and have room for all the parts and to work. You need a power source for the light. Then turn off all fans and air-conditioning or anything that moves air in the house that possible especially in and near the work area. You want as little dust blowing around as possible so nothing settles in the phone as you set up the glue and stuff. Some dust dropped on top of my glass after I layed it on top of the glue drop but nothing between the phone and glass.
