Finished up putting a BSE on my Air and an IS on my iPod.
I'm almost certain they are the same material. The texture and composition of the material seems identical, including the slight "tackyness" (which does make the Air a lot easier to hold btw).
Observations:
- Air looks much better glossy!
- The BSE is cut differently than the IS for the wrist rest area. I believe the IS is composed of 3 pieces: wrist rest, touchpad and touchpad button. The BSE on the other hand is made up of 4 pieces: left/right wrist rest, touchpad and touchpad button. Coverage difference is negligible (~1/2 square inch difference).
- Found no streaks whatesoever with the BSE (i.e. no 24 hour curing period). After application I was waiting for streaks to appear after reading so many application stories here - but none ever did. No bubbles! Not sure if this is due to the composition of the application solution, but I followed the BSE website's recipe using some liquid hand soap. Some streaks on the IS, but to be fair I didn't have the same surface area as the Air, so I couldn't squeegie as effectively.
Tips:
- Don't be afraid to use solution!
- Use a slightly flexible card rather than a stiff credit card to squeegie (I used a library card). This worked great on the tapered edges.
- Dip your card into the solution while squeeging - it'll keep everything gliding nicely.
- Have lots of paper towels on hand
- Really clean the surface well before applying
The IS obviously has a flashier website and makes bolder promises, but IMO that's just marketing - and you pay for it in the marked up price.
Go with a BSE and you won't be disappointed!
