Good E-Juice Calculator?

Alrighty, im still kinda new here. So please forgive me if this question has been asked countless times. Im looking for a good, accurate mixing calculator. Any suggestions? ive noticed some use measurements based on drops, and percentages. But, im interested in calculators that use measurements based on mL since I’ll be using syringes.

Are those Sony VTC4s from RTDvapor.com real?

Hi guys, I purchased my Sony VTC4s from RTDvapor.com since many people recommended rtd vapor as a respected online vendor. Today I finally got them. Based on what I read from how to spot fake Sony batteries at <a href="http://www.sun-vapers.com/how-to-spot-a-fake-sony-vtc5-battery/” target=”_blank” rel=”nofollow”>How to spot a fake Sony VTC5 battery, I am not sure if what I have got are authentic.

So to all the battery experts, could you please help me out? Much appreciated.

Here are the pictures.

My concerns are,

1. The QR codes look too bright and dense.
2. The seem looks like what was in the fake one in the article, <a href="http://www.sun-vapers.com/wp-content/uploads/2014/07/Nasty-Seam.jpg” target=”_blank” rel=”nofollow”>http://www.sun-vapers.com/wp-content…Nasty-Seam.jpg

More pics in the next post since they only allow five in one post.
