  • Simple, solid, no drama
A no drama transaction with a simple, but effective light. A great value work horse.

  • It's my second one, and I love them.
Accidently had my sons Address in Nashville on the order initially and despite trying to change it before it shipped was denied. So now it's up in Nashville and I'll need to figure out best way to get it.

  • Go for it!
I was very skeptical at first because of the bad reviews, but decided to go for it and it paid off. The product came in nicely, well packaged, nothing damaged, everything new and the delivery was very fast. It is an amazing strobe flash! Go for it like me and you won’t regret it.

  • Compact, light, and powerful!
Its a small strobe with a whole lotta punch!! So far, its been great, plus, the price factor is a big plus as far as other brands go. After using my first one, I ended up buying 2 more to compliment my main one. Definitely worth the buy! Check out my sample shot of a recent shoot with a single strobe. ... show more

  • Probably the best and most affordable all purpose light on the market
Absolutely love this product, but i did encounter an issue. I purchased 2 of this from Samy’s Camera in Culver City. On one of the units, the battery isn’t sliding into place and attaching properly. Not sure why this is happening at all. The other unit is perfectly fine and runs super smooth. The power this unit gives off is incredible. Easy to use menus, and the trigger designed for these strobes, is a piece of art. Works for all major camera companies (Sony needs an adapter due to its small hot shoe). $100(ish) cheaper than the Godox AD400, and makes use of all of Westcotts amazing light shaping tools. Also, these strobes are Bowens Mount friendly, so you can use ANY bowens modifiers on it. Came with rechargeable battery, Ac/Dc connection for the battery, 3 magnetic light color correctors, Westcott Mount, and an awesome and rugged carrying case. ... show more

  • Great light and great service
I've been really happy with it. The battery lasts a while. I had one issue with a battery (charging light not working). Call them and immediately got it resolved. Their customer service is great. Once I called in, they FedEx a new battery within two days.

This light seems to have more power than 400 ws and I like it. I just ordered another one.

  • Received a damaged and used product!! Unbelievable!!
The media could not be loaded. Today I received the flash and as you can see in the photos attached, it's not a new product, its used and damaged as well!! There are scratches everywhere - unbelievable!! The mounting part is loose, in this condition I cannot even mount it properly on the C-stand, I'm afraid it will fall apart! As soon as I opened the bag, I could see that somebody just threw the strobe and the cables randomly in it, not caring about damaging or scratching it, not caring about the customer at all. I will try if the flash even works and update this here... but it will definitely go back, I paid for a complete new product and this condition is unacceptable!! ... show more
