There is a thread or two about the 905. Find them and read up. I got "some" for the Swamp Lady. She likes them. They keep improving them.
Now whatever the Swamp Lady likes, the Swamp Lady gets. And Rocket keeps it working.
The atty connector is mounted in a plastic ring that lights up, pretty but do not use as a pry bar or hammer, or put it in a tight pair of jeans (no matter how good you look in tight jeans) or you will break it. She breaks 901s in two all the time
The little black rubber button stick up about twice as high as a normal manual battery button. Pretty easy to press, pretty easy to "side swipe" and lose. Takes a little force to knock it out, but she does it.
I trimmed it down a little, photo in one one the threads in the supplier hype section. This fixed the side swipe problem.
She really likes the 905 and the battery life of the 14500 batteries.
Hope these come in at a good price
Rocket
