Ok, so I've been using Skinomi for around 8 years worth of devices now. I find them to be the most reasonably priced TPU skin manufacturer. I've had the same skin on my Nintendo Wii U since day 1, and still have 2 more in the pack they sent.
They usually give you double the slices compared to thier competition, for nearly 1/3 the cost to you. Then they back up multiple slices with a replacement guarantee.
I've never had a problem with installing these, and nearly never need my second skin. If I do make it to the second skin, it's unlikely that both would have failed. I've rarely needed to fill out a replacement form, when I do, I usually get a replacement skin in the mail within a few weeks and I'm good to go for another 4 years.
Don't go over priced with Zagg. Get a Skinomi! read more
