I'm a lil bummed that I had to return my Zmax today. I noticed the display had lines and was slightly angled. Functionally it was perfect but Varitube is going to fix it for me. And I was surprised because I'm super gentle with my devices and I have not dropped it. When I'm not using it, it's a zipper case. Varitube mentioned they had issues they addressed with sigelei and hopefully they will have them fixed in a V4. =) Kinda sounds like Microsoft. lol.
