I bought two. I took my time and took care fitting. The first one had a flaw in the rubber which when pumped up inside the tyre left a weak area. Solid all around apart from the weak area. Took it off and tried again thinking it was a twist or something. It wasn't. The second tube i inflated before i did anything else and the tube was deformed due to weak and inconsistent rubber. I didn't expect much for the price but i didn't expect to have to throw them into the bin just yet.
cheap
bought two, both faulty
Response of the brand
Dear sir,
Thank you for your feedback. If an innertube is inflated outside of the tyre, it is not necessarily abnormal that it will deform. Inside the the tyre however it is constrained and will not affect your ride. You needn't worry too much about this.
If you are not confident with this product, please feel free to return them to us for a refund or an exchange.
Regards,

As with any bulk purchase, you need to get it right. I've always favoured un-threaded valve bodies, believing the thread and its knurled lock nut to be redundant and a possible cause of tube to valve joint failure.
Valve length needs to be adequate and unless you use very deep section rims these easily meet most requirements. (I run several bikes with a variety of wheel sets in use)
Tubes should be stored in a dark and dry place, thus ensuring, even after a year or so they remain in good condition.
Excellent value, sensible valve length.
Nothing, just what I needed.
Excellent product for the price

If there are threads around the valve so a nut can be screwed on, then it'd be a lot easier to pump up a flat tyre.
Cheap
No threads around the valve
