RF-602 Remote Shutter Switch for Canon 1D/1DS/D0S5D/40D/30D/20D/10D DSLR Cameras
[E18662]

This is a great product. It works right out of the box. I can use it for off-camera flash, or released my 5D shutter remotely. This product should be rated 5 stars if the On/Off switch on the TX unit is built some where else. The reason is that when the 580EX is attached to the TX, I can't use my finger to turn it On or Off.

The package shipped without the PC-PC cable as indicated on the product information from the Best Offer Buy website. I contacted the Customer Service and they are quickly willing to offer $5 refund for the missing cable.
