Hi, I posted some questions here a couple of months ago regarding 3rd party battery grips. I finally\nbit the bullet & bought one for my 450D. It arrived yesterday, I put 2 batteries in it & put it on\nthe camera. So far, it works fine! All the buttons & dials do their jobs, except for an on/off\nswitch, which doesn't seem to do anything so I just leave it off.\n\nFor .99, I think I can live with that!
