[0.575 lb] I use this with a flash bracket and it works! The other trigger doesn't fire with a flash bracket unless you use an extender and bounce everything. This baby works and its easy to fire and go to manual mode. Good thing I have an Iphone or I couldn't adjust the lights from the trigger unless I do it it manually. I do like the ease of no buttons.

[1.5 W] I received this as a bundle with my Profoto A1s Duo Kit. I like this as a complimentary trigger to the AirTTL remote. I plan on using it with my second camera when I shoot weddings. The Connect is super responsive with the B10, A1, and app. Making adjustments is not that difficult. A strength of this trigger happens to be the locking mechanism on the hot shoe. Once you insert it on the hot shoe it has a pin which keeps it secure.

[2.4 to 2.48 GHz] I bought this for use with my two Profoto A1 flashes, which I continue to use and love. I'm not much of a flash photog, but I like to use them for flash fill in our gardens [hummingbirds, insects, and flowers] and for my wife's food images. From Day 1 four years ago, all it has done is just work with my Nikons, and then my Hasselblad X1D, and now my Leica M11, CL, and Q2. I also own the newer Profoto Connect for Leica, but I prefer to use this one overall because it is less obtrusive when shooting, smaller, travel-friendlier, simpler and is USB-C rechargeable [hello Profoto, requiring batteries in the new Pro is not very cool]. And because it just works.

[20 dBm] Exceptionally compact (1.75 dia, 5/8 thick), very light hot shoe mount transmitter, makes off-camera flash amazingly easy. Very easy to use, with only three settings - Auto, Manual of Off. Easy control via iPhone app. I have been using off-camera flash photography since 1980, and it has never been easier. This is a brilliantly conceived and engineered solution, a must have. The bundled offering with an A1x flash is a great value - get one as long as the bundled offer lasts! Highly recommended.

[2.4 to 2.48 GHz] I bought this remote to use with my Profoto B10s. I have had constant issues with my B10s not firing when the light head is close (0-30) to the camera/Air Remote(s). I mostly handhold my light and it's too often in the dead zone and will not fire with either of my two Profoto Air Remote triggers. I'm thrilled to report this new Profoto Connect works 100% of the time no matter how close the B10 head is to the trigger. No frills for sure, but works perfectly for my needs.

[0.8 to 830 Hz] This was a Profoto Connect for the third camera system I own. It works well; I love the small footprint. This specific model rotates a little bit less loosely than my other ones. As result, it is harder to rotate the dial by accident.

[4.75 VDC] I have owned Blizzard lighting in the past and although I don't use their lighting fixtures I DO use their wiCicle Transmitters to connect my lighting software dongle to my lighting fixtures. I have tried many of the cheaper versions available on Amazon and elsewhere only to find out that they don't have a reliable and steady connection to the fixtures. The official Blizzard wiCICLE transmitters seem to communicate better and last longer. Yes they too are made in China but perhaps with some better components. They also made an improvement when changing the color frequency it is now a button rather than having to take a paperclip or bobby pin in the hole. I hope this helps!

[0.8 to 830 Hz] Works astonishingly well straight out of the box. I never need to open the app on my phone for adjustments. I just adjust everything by hand after swapping to manual. The ttl is amazing. I actually use it much more often than I thought I would.

[4.75 VDC] Using in divisible meeting space in crowded 2.4GHz environment and works fine. Very cost effective and simply works.

[1.5 W] Simple! Low Profile on camera! Easy to use. Battery lasts for days of use.
