Same technology only difference is the price. No where on Zagg does it say it won't yellow yet on the other site it specifically state's 'won't yellow like other products from our competitors', which is good enough for me.

Funny thing as I'm typing this email just got an email from Zagg. I replied to them on Wednesday morning telling them to cancel my order yet they refused to respond to email until now. They used the excuse 'sorry we didn't get to your email sooner but if you want to return your order as it is on the loading dock already to be shipped out, you'll have to pay for the return shipping'--meh, it's fine with me, $3.95 shipping back but I'll still save $17 by returning it an ordering the other one at $7.
