Mine is fine I wouldn't say it's wiggly or loose. Possibly not "sturdy" enough to stand the test of time IMHO. But I could be wrong. One thing I don't like about Samsung devices is the lack of a sturdy power button. They all feel mushy and not very distinct. The Gear is not bad though. I've felt worse Samsung power buttons. Use an iPhone power button a few times. Now that is a solid power button pressing experience. Feels sturdy, but with a good tactile feedback.
haha. Nerd alert.
