but after reading Anna's posts about it, I guess I'll have to try.
If I can not brick something with an update, I'm fairly certain it is easy. My hardest two things were a) finding the USB port (up top) and well concealed, and holding down the "Plus" button while attaching both my USB connections. However, the Geekvape website makes it really easy, although I did have to download some free "unzip" software my computer is running on a very minimalist platform, kind of like how cars with the "base model" are pretty rudimentary.
But the actual update was easy.
Good luck it really is worth it for battery life, I was getting SUPREMELY poor battery life (and while resting, mainly as my wattage is on "11" and even doing stuff like turning it off at night, well I was getting maybe just under two days. Without turning it off on with the update my first pair of batteries lasted almost 4 days.
Good luck!
