hi
i got that same remote off ebay
it's useful, thin and light
the only problem with it is that it doesn't handle bulb exposures
it just takes the picture, so the max exposure you can use is 30 seconds
there's this one from hk, which says it does handle bulb exposures, and it's pretty much the same price (i only saw this after i got the other one, i might still get this one sometime)
Universal Multi Remote Control for Canon/Nikon/Pentax
bonus is if you have a nikon or canon camera, it should work with them too
