I can't remember if we bought these or were sent a case to try, but I came across Update in my company's office fridge/pantry.
PROS:
- The unboxing and packaging experience is really cool.
- The product description on their website is pretty accurate - the drinks taste more like a flavored seltzer water than a fake-flavor energy drink. I actually liked this, because I feel I feel like most energy drinks taste like chemicals.
- I dig that they're zero sugar
- Didn't get a crash after (but also didn't feel as focused as caffeine based energy drinks?)
CONS:
- I tried all 4 flavors, and I pretty much only liked the peach one.
- If your body is used to drinking caffeine regularly, you're probably going to get headaches until you go through the "withdrawal" period. These are caffeine - free
- IMO, less powerful than caffeine-based energy drinks
TLDR: Probably wouldn't buy again unless I was trying to go off caffeine forever OR they changed their flavors.
