Cheap ND filters

Anyone bought these or know if they are any good? Price seems particularly good but that could mean they are bad.

For 10 quid it might just be worth buying them and shooting in RAW to see if you can fix the color cast.
Though, I'd just buy the B+W ones from maxsaver for not a lot more tbh.
