Awesome strobes, solid build quality

Bought 3 of these for sports work and corporate work and have been happy with them already. Significant upgrade from the Flashpoint 400 I had constant battery issues with and also love the interface and trigger to use them a lot better.

Highly Recommended

FJ400 is PERFECT for what I need it for, and the trigger is so easy to use. I have several of these and very user friendly from attachments to adjusting light settings. Highly recommend.

Westcott FJ400 performs as expected, but be weary of bundles

This is my 4th FJ400. I decided to continue with Westcott due to their performance and quality. While there are no complaints with other brands such as Godox/Flashpoint or higher priced companies, sticking with one ecosystem was a focus. The FJ400 sells itself. There are hundreds of reviews so I will spare the fluff. The Glow EZ was a great addition to my modifier inventory. It was my first one and honestly, may surpass the primary use of the Manny Ortiz beauty dish. The inclusion of a grid, the access zipper and just quality of the material impressed me most. The Flashpoint lightstand is the most disappointing part of this bundle outside of it taking nearly a month to receive all the items from the time of purchase. It's NOT heavy duty. The included Westcott lightstands that came with my location kit, outperform the Flashpoint in every way. Though the weight rating may support the mounting of the soft box and FJ400, I simply do not trust it. It wobbles at every height.

Dope strobe!

Amazing strobe, and a good start to the Wescott ecosystem! I also have two 200?s and an 80 and they all work seamlessly with the trigger for my Sony cameras.

An excellent combo!

A well timed combo to have function of these awesome lights. They are so simple to use and the universal setting on the trigger makes this a must have if working with different cameras. The FJ400 is such an amazing light. I can not imagine using anything else right now!

A upgrade on the lighting

Hands down one of the best external flashes I have used in my photography career. It's so simple to use and with the trigger changing power on the fly has never been easier for me. I have so much more to learn with this flash, but I cannot wait to master it!

Great light at a reasonable price

I love my new Westcott FJ400. This light makes things easier allowing me to control its output by remote. Once set my exposures are very accurate with no variations from flash to flash. I plan on buying more of these to replace my old mono light system.

Nice studio or on location strobe.

I really like this strobe, when fully charged you get 400+ flashes, you can also leave it plugged in if you want. Great for studio and on location shoots.

Very nice studio or portable Strobe with universal trigger

I really love this strobe, works great in the studio plugged in or you can take it on location. The battery lasts a long time. Price is right.

Very nice light

I really like my new FJ400. My old mono lights all work but none have remote control. With this light I will begin to build a radio remote light system. So far the light has been wonderful. Light readings have been consistent with the power set. The remote functions well and it has made my shooting easier with remote control of the one main light that usually requires me to go up and down on a step ladder to adjust. No more up and down with this well equipped light. Everyone pretty much sells it at the same price but Adorama has about a fifty dollar savings advantage when buying the FJ400 together with the remote. My only problem is getting my computer to link with their firmware update, but I?m not a computer nerd and I?ll will eventually figure out what I?m doing wrong with the firmware update. My target is to add three more of these FJ400?s.

Happy I chose Westscott for my OCF needs

Works great! Easy to use. I love the display. The system is easy to use. When using the modeling light the fan is quiet but not enough for video. That's fine because I bought it pics. (Note- I haven't tried this in HSS yet only TTL and manual mode.)
