Other Thoughts:The Remote Control Shutter works as advertised - very easy to use. No on/off button, but it's not necessary - I leave it on all the time. The price is so cheap I thought "no way" - but after several very long astrophotography sessions I'm sold on this remote.
Other Thoughts:At first thought, it is a little large for what it is, but it fits my hand ok and after a little time I got used to it. My only real issue is that I should like to have had a longer cord, and the connector fits kinda loosely in my A450. All-in-all, it's well worth the price.
