Early foray into the world of AliExpress. basically for £30, they are OK. If you consider that a set from Motorrad will set you back £180...they are fine.
I just had some delivered from aliexpress too - I used kemimoto as their GSA stuff seems to be very good. The quality of the liner bags are heavy duty and I am very happy with them. If you want liner bags, then I would highly recommend them.
