Hmmm. Okay, here's first impressions.
--Looks almost exactly like the 510 I already have, which is what I was looking for. (Black with purple light)
--Was a bit disappointed when I found I got a manual battery when I was expecting automatic. Was REALLY disappointed when I found out that I ordered a manual batt by mistake. lol That's okay, I do like manual batts too. Next batt is an auto.
--Tried all the sample flavors I got. Kinda like Cowboy and Ry4. None of them really knocked my socks off, but that's okay. None of them were horrible either.
--The flavors taste a bit harsh, but I'm pretty sure that's because I got 24mg when I probably should have gotten 18mg. All I could do was guess.
--Batt came fully charged, which was awesome because I'd just run out of analogs.
Well, that's most of the first impressions. Let's see how long the batt lasts (I got the bigger one).
