I ussually shoot in remote locations in the mountains, and I often find myself shooting around lakes, creeks and rivers. I lose or break several strobes a year do to the relatively harsh environment I shoot in on a regular basis.

Reliable seller. Flash is undamaged and works perfectly fine.

Delivered in 2 working days; Genuine speedlite, works fine

Great flash. Good size, easy to use and understand functions. Information booklet limited but contains everything you need. Works well. Highly recommended!!

I had 2 of them. Both broke after about 2 months use. I spent a ton of money on these cheap chinese Yongnuo flashes and are only good for 1 time use or very light use my amateurs. They can't withstand use by professionals.

Clever capable and reasonably priced from the purchaser I bought it from. Although I am still learning how to pilot thing it has a zoom function which allows you to adjust the focal length on the flash you can network up to 4 of them together if you want a floodlight effect through a set area.

I have had 4 of these, they are just great. I needed a compact flash setup to carry in my camera backpack while skating around the city. I shoot skateboarding and these are very convenient on the go. Just turn them, set power, zoom, and position.

Powerful; Reliable; Easy to use multiple flashes with only one rf603 trigger on camera (they have a built in reciever); Can freeze action at lower power levels; Solid build; Easy to use; Zoom

HSS not possible on Pentax; Entirely manual

The last flash I owned was a Sunpak. I am amazed how fast this flash charges and how powerful it is compared to the old compact flashes. I don't like to use flash and didn't want to spend a lot of money, so I picked this unit. This flash is solidly made and has a lot of features for the money.
