    Very nice flash for the money. The cameras remote functions work well. The only negative is the plastic diffuser was misshapen on both the units I purchased and would not fit over flash. Put them in boiling water for a few seconds and reshaped them, problem solved.

    It does what it needs to do. It's worked just fine as kickers and hair lights to compliment my strobes. Currently own 2.

    I have used Canon SpeedLites for years, but forgot mine while I was out of town. This SunPak worked as well as my Canon external flashes during the trip. I can't speak to it's long term durability, but it feels solid. I wish I had known about it sooner. I will use it in conjunction with my SpeedLite because it has master/slave functionality.
