Dot Line Corp. Slave with Hot Shoe

At first glance, the DL0129 hot shoe slave appears to be a steal: inexpensive, wireless remote hot shoe slave. Unfortunately, I've found that the flash pickup sensor does not always work, and when it does, it's not able to fire the flash quickly enough to make a difference in the photo. (The delays appear to be as slow as 1/5 to 1/15 of a second.)If you're doing some very specific long-exposure shots that require a fill flash (ie., to "freeze" some action), this might work. Otherwise, pay a little more and get a hot shoe slave that works for a majority of situations.

Unreliable and doesn't trigger the attached flash quickly enough to be useful.
