Hello to you all. I'm in the want for a case for my phone that fits on my arm this way I don't need to hold the phone while using my cane and I can run, or walk or what not and still take video and stuff. I want the case though to have a tight fit this way if I'm running the phone won't slip off my hand. I've never heard of these until last year so am curious as to how these work. I also want to still be able to use the phone in said case, if I need to of corse.
