Bests & Worsts Reviews from Amazon

This flash does what it shound but don't expect wonders. It essentially "brightens" your flash photo. I am using it with a PowerShot S2 IS. When reading reviews, you might see it said that this is a wireless flash. While true, that's a bit misleading. The flash works by simply sensing that the primary flash has occurred and then firing as well. This means that you *must* fire the primary flash to have it work. Another thing that you might read is that this flash "focuses". I can't imagine what the reviewers mean. This is a simple slave flash. You can set the "range" in 3 basic increments but that seems to be it for adjustments. The manual is slim and gives no hint that there is anything sophisticated occurring. A few notes: - The flash is very compact and lightweight. - You can easily hold the flash in your hand to position it for better coverage. - The recharge time is extremely fast with a new battery -- essentially immediate. - It uses a non-rechargable lithium battery. These tend to be pretty expensive. The manual says it will get over 250 flashes on a battery. - This flash *does not* eliminate the shadow that the PowerShot S2 IS wide angle lens creates. It does reduce the shadow. Overall this is a good flash but seems a bit pricey.
