10ltr bucket of perlite UKGROW, Black

The media could not be loaded.  I took a risk on this after I saw reviews for the 5 litre which were not great. Firstly there is no labelling on this white bucket which is stated as black. So how do i know this is definatly perlite. I will try it on a plant I don't particularly like. I should send it back really as this is a 10 litre bucket and it's only just over half filled as can be seen in my Vidio. Looks like it's been stored badly. I certainly won't be buying from these again. I was wary as the advertizing picture only showed a picture of course perlite and not the black bucket which was advertised. There were no reviews at all for this so I knew I was taking a risk. I just hope that it does not kill my plants. I wouldn't buy an unlabelled item from a garden centre so i shouldnt accept this either. If i could get to the po i would send it back and if i wasnt in need of perlite in a hurry. EDIT.Jan.28th.23. Well plants are alive and it's doing the job. It is perlite but I still would not repurchase due to the bucket being half filled and unlabelled.
