Stander df-550 universal SLR camera flash Canon 6d works well?

The hot shoe of this flash has only one contact, which can be used on any SLR with hot shoes, but it can't be recognized by the fuselage like a multi-contact special lamp. The shutter speed of the flash synchronization is automatically adjusted by the fuselage. The light can adjust the flash output in multiple stages, which belongs to pure manual flash and does not support TTL flash, so it may not be suitable for novices. Some domestic compatible lamps can support Canon eTTL flash, such as a Canon special lamp with different colors, which is inexpensive and convenient to use.
