Just got er' back, vaping away on it now. The new window screen looks clear as a bell and different from the original. Seems thicker, more sturdy, and clearer than before. I never really vaped this thing on a standard atty. So, while it was gone, I ordered some 2.3 ohm attys, and I must say its a toss up between LR cartomizers(dual coil) at 3.9~4.0V and standard res attys at 4.6~4.7V. About the same vapor production, but I think the DCHV carto's have more flavor to them. Thats the good thing about this device is the ability to try some LR and Standard atty's and just kida play with it till it works for you. Soooo..I got 10 standard 2.3ohm atty's to go through, then I guess I will order more DCHV cartomizers .......Vape on!
