I've bought two of them. The first one started to go really wonky. It would change settings while in the middle of a shoot. As in you could sit there and watch the numbers on the LCD start to change... really messed up a number of my timelapse shoots...
A new battery seemed to fix the issue for the most part, but it would still do that occasionally.
The second one I got seemed to work alright, but I've seen it do the same thing occasionally.
Like knock-off PW's, it seems that these remotes do function for the most part, but if you really depend upon them to be reliable and functional, go for the real deal.
Just my two cents.
