I'm very happy with mine - it's my main vape.
While you're waiting for it to arrive go to dealextreme.com and buy some extra
batteries and maybe an extra charger. Trog has the details on his forum of what he recommends for you to buy.
Wish I had been told that when I ordered my SD. My SD arrived with batts that were barely alive and wouldn't hold a charge. So I had to wait til I got the batts I ordered to find out how awesome the SD is. I had no idea that these batts weren't available in the US and I couldn't hop over to the local whatever store to get new batts. Live and learn for sure!
Now that I'm trog-savvy, think I might just get another SD. This thing is built solid!! Reminds me of those Ford "Built To Last" commercials.
The only problem is I don't take the SD with me when I'm out and about. My kids told me it looks like I'm smoking something illegal - hahaha - like I'm smoking liquid weed or something. Too funny!
