Anyone know what It means when you go to fire the v3 and the screen just goes to saying sigelei for like 10-15 seconds/ locks up and you have to wait and do 5 click restart or pull the battery?
That you have a faulty battery connection, maybe? Is the "telescope" screwed up tight enough? Are you using good, unprotected batteries? Do you press too many times in a short interval to make it fire (but then it just changes the settings, I think) ?
If none of the above it's probably faulty...change it at the place you bought it, or at least contact them.
I bought mine from Heaven gifts, OK it's in China, but they seem to be real Sigelei's, solid SS, same in all regards. The first one had a problem, in that it changed the Wattage when it wanted. Most disagreeable, as you're vaping away at 4.5W, and you take a puff, it's at 12W! You can imagine the effect!
Any how, I'd ordered some other stuff, paying the postage express, so they put in a new one, which works really well.
They do have the V5, but I don't really want to charge my telephone with my PV which is in what they've changed. It's at under 50$, and the V3 under 40, so YES

it is a great affair, great mod, although I'm waiting on a V5 Vamo too. I've had Vamos since they came out and find them pretty reliable, tough, and thoroughly great Mods.
But I must admit with a telescopic Mod you don't have extra 'bits' of it lying around, as you do with 18350 batteries in the Vamo.
Also the 1 button Menu has certain advantages over the 3 buttons, such as not pressing on the wrong button and changing the settings, and ... that's about it, except for the telescopic form of the Sigelei.
All my Mecha Mods are telescopic, and I find it's a form of PV that should have been around for much longer, it's so practical

If you get one from where I got mine, the free post is LONG, and by long I mean a few weeks long, but for 16$ you can get it sent in a few days. It's not excessive, and saves a few weeks waiting.
Now people will say I've gone for a Chinese clone, BUT where do you think your local vendor buys his stock, honestly? I don't have any reason to think it's a clone, as it's sold as genuine Sigelei, and when they sell clones they say "Clone of ...", and I've been buying there for a while. So don't bother posting to say that, unless you can't control yourself
Happy Vaping, a all my good wishes for the approaching fetes, Xmas, 2014 (OMG, I don't believe it, it's the age of Sci-FI

) and all that, the Winter Solstice, most of all, as the days will get longer, and summer will arrive
