If someone is looking at these they have a 3 day sale, code = NewLeaf. The discount is 23%, not bad.
Also, I mentioned in this thread (I think) about the $30 one I ordered (not from V4L) and I got it today and i do NOT like it. So maybe V4L is the way to go...I assume they are better but I have never tried it. Perhaps I just do not like the KR808 - that is also a possibility. I just do not know.
Not all 808s are created equal, or any other pv for that matter. V4L does have an influence at the supplier, and the batteries are not standard, nor are their cartos.
