Its plastic is very fragile.. the clasp broke immediately, the striker works with the little knife, as for the compass I don't see it working, the cord will do its job when needed. For one euro it's okay.

A product at the price of a "coffee to go", which offers a lot and therefore is worth it and more.
4 stars because the compass does not work correctly at all, so one cannot rely on its indications, and also because the plastic parts seem relatively fragile (hopefully I will be proven wrong on this).
The good things about it? Everything else. Very sharp knife, a strong whistle - I blew it loudly in a closed space and my ears buzzed a little - and a sparkler that works properly with the serrated back of the small knife.
As for the bracelet rope, I cannot give an opinion as I did not try it.
In conclusion; Get it without hesitation.

There is no way to adjust and open or close according to the size of the wrist. It is a standard size. However, for its price, it is satisfactory.

Very good for its price, the knife needs a little sharpening but otherwise it is very good and I recommend it

It has a compass, whistle, knife, fire starter, and a rope of about 4 meters. Very good choice, I highly recommend it!
Note that the plastic of the fire starter has a loop to fit on the wrist, it is not defective as the friend wrote in another comment. Also, the knife is very sharp and cuts like a razor! The fire starter is difficult to use due to its size, but in case of need, it does its job with effort!

The opener doesn't work, the material is not good, the knife doesn't cut... and overall it's not good. (The opener was also crooked and scratched, I don't know to what extent it looks crooked in the photo.)
