The manual is available in English and Mandarin, and for those who have difficulty reading one of these two languages, the operation of an interval timer is usually standard and many tutorials are available online. In addition, use is fairly intuitive and you soon figure out its operation a little fiddling.
Concretely, I mainly use it to make timelapse and I have until now had no problems (except once or he would not stop to take pictures and put out, he then simply open the battery compartment and remove one).
The product is simple and lightweight.
No need to buy a more expensive product, especially if you have a tight budget, where it asks what one pays more (if not the prestige of the brand?).
