Very simple to use and the rotating cold shoes let me adjust the flashes' IR sensors toward the controller for perfect communication every time. Can use for 1, 2 or 3 speedlights in a modifier. I did have to repair one of the cold shoes, as it came with the screws mis-threaded and I couldn't tighten it around the foot of the flash, but that's about the only issue I've had. Some parts are made of plastic, albeit durable plastic, so I recommend keeping it protected in your grip bag. I keep mine in its own padded case when in transit.

Update 6/16/2014:

The cold shoes keep sticking - cannot get them to open or close. I've had to repair 2 out of 3 cold shoes several times. Surprised Lastolite had such poor QC or that Mr. McNally would put his name on this twitchy product :-(  Buying ePhoto version instead - better reviews and less expensive.

Without this device my LED turn signal would only quick flash.  This makes the turn signal computer think it is running regular bulbs.

Excellent product! It has a nice soft tone, and fixed the hyper flash issue. Only weird thing is that after the turn signal turns off it will make an extra click or two, but that's really no big deal. I 100% recommend!

Worked great. Word of caution, use sparingly and really try using a mold if you can. Not using a mold you risk getting glue on the internals and the front facing camera. The flash light is used to 'spot-treat', for example, one you have a corner full set in the glue, shine the flash light over it to hold, 20 sec. doe this on all corner until glue is set and then place under UV light or full Sunshine.

I was taking pictures at a bowling alley birthday party for my daughter's friend a couple of years ago with the included, but tiny FL-LM1.  The dark of the bowling alley was too much for the flash. Even at ISO 800 and 1600, the shutter was still too slow to catch moving kids and I wound up closing up shop for the day after maybe 20 pix.  Theme is consistent with the E-PL5; anywhere that is illumination challenged pix were bound to be spotty.

Best gamble I took on Amazon to this day!  The NW320 seems sturdy and well made and for less than $100 I couldn't complain. Returning to the same bowling alley for my daughter's birthday party, this flash was able to cut through the dark on ISO 200 capturing kids in action at distance.

Even after 250 pix, I didn't notice any recharge lag.  This was 1 day out of the box with NO re-configuring any of the settings. I know, I should not have done this, but the flash still performed remarkably well.  The only thing I did change was to update the Oly's firmware to v1.5 since this was a newer model (no pun intended) flash.  This flash really extended the usefulness of the E-PL5 and now tips the scales in its favor.  Now my 40D is being reconsidered for the eBay pile. (just the body... I know, who wants an 8yo 10mp full sized DSLR body these days...)  I'll do some fine tuning on the flash/camera settings and and check to see what firmware updates are available (has USB port for updating) and report back. Also note that this flash comes with a diffuser (which I forgot to use...) and has a metal hotshoe.  I recall my first Canon Speedlite (old 177A on my AE1) broke two plastic shoes and left me stranded.  I don't expect the world, just at least 2 ~ 3 years of use, or if I'm lucky I can still use after 35 years like my Speelite 177A!

Easy install and cured my "hyper flash" problem with my turn signals after I installed LED bulbs. So much better than using resistors.

Had these in in under an hour. Had to do a little body modification in the tail light pocket to get the plug and reverse light led driver tucked back into the cavity behind the pocket but other than that everything went smooth. I found out that I DIDN'T need the blinker relay or any in line resistors. No "hyper flash" at all.

flash reflects in the chromed window ruining photos

Won't stay on flash, must be taped, poor tolerances in molding

It's really easy to set on your external flash device, but mine came with a stain/scratch o  the white square... :s
Although it works perfectly

Neat little gadget...solved the lighting problem.

Works perfectly to trigger off-camera flashes.  Have a bit of a Rube-Goldberg setup using remote triggers, strobes and flashes and needed an optical input in one area.

I plugged it in.  It blinks at the correct rate!  What else is there to say?  It does everything it says it will and gets rid of the "hyper flash" by using LED bulbs.

I have a 2001 Chevy Venture that starting having some issues with the back tail light. I noticed when I pressed the brake, both blinker lights on the dash would light up. Also when I pushed the brake and had the turn signal on, it would go fast, as though the bulb was out, even though it wasn't. Let off the brake and it would go back to normal. Then at times the tail-light and brake light would alternate in the back when I had the turn signal on. After doing a google search, I found people have these problems when this part becomes damaged. My husband pulled it out, and yep, we noticed one of the little prongs had melted. He jerry-rigged it by putting some bulb-grease on it and doing some other modifications, which solved the problem for about 6 months, then it started again. Found these on amazon for a decent price so decided to give it a try. Installation was pretty easy (easier for me even as I sent my hubby out to do it!), and totally resolved the issues we were having. If only changing the leaky oil pan was as cheap and easy...

It's pretty great but takes a minute to warm up for all the colors and settings to work properly.
Strobe and flash are pretty much the same exact thing though, the light continually blinks to a new color after a few seconds and stays for a few seconds before blinking to another one again.
