Works great and easy to use
 

I got this for use with time lapse and long exposures. Simple to use and does the job well. I haven't found anything yet that it doesn't do...other than turn off that is. The down side is there isn't a power Wireless Timer Remote for Nikon amount. It would have been simple enough for Canon to install even just a switch. If it weren't for this I wold have given it 5 stars.
