Query: Just not worth it

Though the price is right, I didn't like the final results. I tried putting this on my Zune at least a dozen times and couldn't keep from getting dust, a fingerprint or something under it. I also couldn't get it to slide all the bubbles out. I finally went and ordered an invisibleSHIELD and though it was considerably more in price, the ease of putting it on (flawless the 1st time) was worth the extra money.
