A good large top box for little money.
No fitting instructions but if you can't fit this without them you shouldn't be riding a bike.
Seems a little delicate but with care it should last a long time.
Says it can fit 2 helmets but it's squeeze, but we have 2 flip helmets so they are a bit larger.
Fitting rack is good but will rust eventually, just take care when fitting.
This one comes with a small back rest as well, wife says it's OK.
Good security, you wont get this nicked quickly, locking it is a bit fiddly.
