I had this for a while before i stopped using hi-caps and my expirience with it has been just short of perfect. First off, I was the kind of person who would spray through the woods without the slightest bit of descretion, i kept the auto winder in my front pouch so i could easily pick it up and wind away. It took about 3 seconds to fully wind my magazines which not only made it perfect for desparate situations but also great for game preps, not having to waste the time winding all the magazines before a game. The only thing i didn't like about it was when i got rid of my 'spray and pray' tactics and started to be a bit more silent. The thing is very sensative and there's no off switch so it would go off in my pocket if i tried to lay down, in an open pocket it's really loud and can completely giv away your position, but then again it also sparked some laughter. Either way, i don't use hi-caps any more and i sold the auto winder on ebay, but i would definetly recommend it to anyone with the 'spray and pray' attitude!
winds up a magazine in 3 seconds
extremely easy to use
...i don't know how it could possibly break a magazine unless you kep it winding too long
about the size of the palm of my hand
no off switch
