Well, I finally received Version 2.5; the *same day* the first kit you sent to me arrived, so I now have 2 versions.
Great! Now you can do comparison if you like, although functionally you probably won't find much difference.
Will you kindly repost the links to the blind-friendly user instruction videos? I am so mechanically inept that I can't seem to figure out how to use these things.
OK, I will include a link to the video I was referencing. First, remember that video references the very first version of the
Cartomizerfilinator -- before I even started calling it that.

So, do a little preparation first:
1. Find the adapters that I sent, which feel like rubber tubes that are open on end and have a hard plastic piece on the opposite end.
2. The hard plastic piece is designed to screw into the tip end of the syringe that I sent. You should be able to get it inserted by feel, and when aligned properly it will screw in about one to two full turns. Screw it in until it is just a bit more than finger-tight.
When listening to the video, the assembled syringe and adapter that you have are basically the same as what I refer to in the video as a "syringe with a luer lock tip that has been modified" or "one piece unit" or "pre-manufactured syringe".
Also, toward the end I mention something about pinching the tube to make sure it does not come off of the syringe. You will not have to do that because the version you have actually screws into the syringe and will not just pop off.
The last tip I have is that your kit came with another tube about three and a half inches long that is smaller on one end than the other. This tubing is not mentioned in the video because I had not come up with it yet.
The large end of that tube can, if you wish, be put on the end of the cartomizer opposite of the syringe so that the small end of the tube can be dipped into the nicquid or
e-liquid rather than the cartomizer itself. You might try it both with and without that tubing to see which way works best for you.
I'm sure you will come up with a better or more efficient way to do this after you have tried it a few times, but other than the differences I mentioned above this procedure should get you started.
Finally, if you think it would be worth doing another video or recording with more specific or precise instructions, please let me know and perhaps we can go over the details to make sure it covers everything a blind person needs to get going.
With all of that said, here is the link to the video at the point where I begin to describe the actual procedure. Please let us know how it goes for you!
