The tire iron I've tried - do their duty without complaint.
The tube I have not yet needed - but Continental hoses have a good reputation, here I am unconcerned.
The bag is very easy to attach and detach under the saddle, making the Velcro fasteners but not the most stable impression, so 1 star deduction.
For the price ok. However you get for a few euros more and higher-quality utensils for your bike.
