I was reading this prouducts info. I was just wondering if anyone has tried these? I know they have to be charged, but they state they will last all nite. I don't like the statement to keep a lite by your bed to quickly charge them, come on. I like the daytime inserts though, just what my PT needs. Price is cheap, I spend more than that on beer sittin here typing to yall. Let me know if anyone has any info.
