That looks like a generic copy , so I am not familiar with it .
Its possible it can work , nice to have both hot air & soldering tip .
I call it kind of a truism , it takes more skill to make a cheap tool work than it does a quality tool .
If try to learn with a cheap tool , you may get frustrated and quit leaning , or pickup bad habits from using the cheap stuff .
I would suggest learning to solder / desolder with scrap boards that you would not even try to make work , then when you get some skill developed , try on board / component that you do not value , but is in working order , so as to see if you can get a valued board / component working after desoldering and resoldered inplace .
If you try to learn on something that you value , it may get beyond repair - through the learning process - so start with scrap boards / components .
