This is a cheap, yet versatile and dependable speedlight, although it requires some skill and proficiency from the photographer.
Ranked in these QuestionsQuestion Ranking
Pro Very good value for the money
The TT560 costs only a little over $30 but it has a very durable, robust housing. It also has some useful features that you can rarely find in budget speedlights, like battery saver and overheating protection.
Pro It has protection against overheating
If the inner circuits begin to overheat (usually happens if you trigger it more than 10 times within a minute), the flash will turn off automatically to prevent a malfunction. It will turn itself back on when it's cooled down sufficiently.
Pro It can be used in sync with other flashes
In slave mode, this flash can be triggered by the light coming from other speedlights. Useful if you need several light sources.
Pro Wide range of supported devices
This flash has an ISO hot shoe that works with Canon Digital EOS, Nikon, Olympus, Panasonic, Pentax and most other DSLR cameras. Although it's a good idea to double-check if it's compatible with your camera in terms of voltage.
Con It's not suited for begineer photographers
The TT560 has no TTL mode that automatically adjusts the power of the flash depending on the conditions of each shot. For an amateur, tinkering with the settings of the flash to match the width of the aperture, distance to the object, and other variables can be overwhelming.
Con It's not suited to take zoomed images
Since there is no zoom on the speedlight, using zoom on your lens will result in wasting a lot of light on an area that will not make it into the shot, while the scene you're focusing on may remain poorly lit.
Con It's not well-equipped to take quick motion and wide aperture photos
The flash lacks High-Speed Sync (HSS) feature that allows catching rapid movement on a photo without blur. HSS is also useful for taking wide-aperture photos, where the object is sharp and the background is blurred.
Con The user's manual is incomprehensive
The user's guide lacks some important aspects of using this device, for example, it doesn't say anything about how to use an external power source and which sources are compatible with the device.
