I've heard bad things about the tubes, most of the tools feel like they're made of cheese, the bells are loud but have a plastic axle that snaps or comes loose on our rough roads and then you can't fix it.
On the flip side, the self adhesive patches work, the bottle cages seem OK, they sell large 900ml bottles and the BMX brake blocks are so soft that they work OK on steel rims at a push. The chains are TAYA which are usually OK (open the box to check) but I've not bought one.
Why bother with the tyres, oils or cleaners? The base products of known brands aren't much dearer.
