Welcome Chris, and congrats on your successful 4 months. I also use a Vision Spinner with Evods and like the set up very much. It's easy and convenient for me to use and does the job - no smokes for me for almost 2 months!
When I ordered my Spinner they were out of the larger sizes, and I worried about getting the 650. It's been great, and since I am home a lot, charging it hasn't been a problem. Also, I did get two of them, so I have one ready to go most of the time. The smaller size is nice for when I go out, too.
