I graduated to the Echo from the Blu cigs & the difference is night & day. I recommend getting a couple of the 1100 batteries for heavy vapers. Also, be sure to purchase juice in 30ml bottles. You'll kill a 10ml bottle in 2 or 3 refills. Finally, be sure to replace your cartos with every 30ml of juice you use. They're cheap & a fresh carto will always provide the best vapor & throat hit.
I've been researching other brands & models, but I've decided I'm going to stick with the Echo!
