Yes that is right, I used to have better ones but find for what i want to do these are fine so my son has my best outfit.The ONLY problem is that you can not use the NIKON remote triggers for the camera with these plugged in.

Does not sync at 250th, only up to 200th with a D850 and manual studio flash heads.Advertises capable of up to 250th.

I use it for nikon D810 using the 10 pin connector. Everything works well and as expected. It took me a while to figure out that off camera flash cannot be triggered in sync with camera using remote receivers on both camera and flash. To solve this, I triggered the off-camera flash with the pop-up flash on-camera. (set up as fill or commander only) and that worked very well with Yongnou manual flash. It has made my set up quite a bit more capable.

stopped working after 3 times

Fantastic and unique set that works perfectly with my Nikon and Fuji gear and studio lights. Please note that despite appearances, these do not transmit ttl info

Item doesn't trigger the flash at correct time with the Nikon D500. I've bought the same product twice and had the same issue both times despite ensuring the shutter speed was below 1/200s and trying out different radio channels. The flash would fire but too early. I haven't tried with another camera so cannot comment if this is a general issue or specific to the D500To the seller: Please remove the D500 compatibility from the product description as it clearly isn't.
