LCD Timer for Canon EOS 550D etc.

The only drawback: There is no off switch.
Although this appears to be a relatively unimportant gripe,
because if you can believe the instruction manual,
the battery has a lifespan of about 3 years.

The instructions are only in English and Chinese.
One criticism, the appeal to many ... but I find unnecessary.
The operation is quite simple anyway. It comes with a bit
"Trial and error" even as their destination.
And let's face it: English is now no Kiswahili. ;-)

Overall, a buy recommendation for one-third of the price
Canon TC-80N3. Price / Performance-wise so good! :-)

Long-term tests do I have to do, should notice something,
I make an addendum. ;-)
