Extremely low-quality construction.
Some key commands didn't work from the start.
The battery compartment was slightly smaller than normal, resulting in not being able to remove the batteries once you placed them (with difficulty).
It was thrown away the same day and a corresponding one was purchased, of course at double the price (around 14 euros) which worked perfectly from the first moment, without any of the above issues.
I may have just had a bad experience, but this is my experience with this particular type.
