Great reliability and features.

I am not sure how three people gave bad reviews about having link problems. I have used this and the former model and the new R model and have never had a problem. I use the flashes in nature photography often in tough environments; sometimes with up to six flashes though normally with 2 or 3. They perform with great precision and never had a problem of any type. As a professional photographer I rely on this system and can highly recommend it for all flash uses.

Not reliable and constant dropped connections

The canon radio “RT” system is completely useless. Whatever radio frequency they use is completely crowded now in 2025. You will get inconsistent connections. Their speedlites constantly loose “link” in the middle of events. This has been an issue for many years and there is still no fix.

do not buy

Why are they selling this garbage? Never holds a connection, if you're lucky enough to get one at all.

Unreliable

The whole flash system is unreliable. They will lose connection in a newer wifi environment. I used to rely on this system, but no more. Canon will not even acknolwedge the issues, even though the customer forum has hundreds of posts on this topic.
