I just got my TW compact red kit, 1 atty, 1 batt, 3 carts with a 13ml bottle and a usb charger for $40 something with shipping. Now this is my first TW 510 but I have others and I gotta say this one hits better and the batt I would say is a little better then a few others I had or maybe its just me. But for the $ I love it. They was fast with shipping it and I didn't have to charge it for 8hrs like others. I gotta say I love the feel of it and of course the look
So if your looking for a backup and don't wanna get the whole kit this one isn't bad for the $ so give it a look.
