    Misleading title, unsuitable product and poor customer support
  

*by M***S on Reviewed in the United Kingdom 🇬🇧 on 8 February 2022*

I searched for black lava rock and the title read: black rock grill 1-3cm lava rock so I had taken that to mean it was black lava rock! When I opened the bag and discovered ref rocks, I checked the listing and realised this was the brand / seller name 🙄 I contacted to alert the seller in the hope of an apology and the listing being amended! There was no other mention of colour in the listing! I advised it should be in the title and in the description that it’s red. The product is extremely dusty so takes a huge amount of washing to be usable in a tank (personally I feel this should be stated too as other rock doesn’t come like this). The seller was informed that I had opened the bag and tried washing the product. He didn’t apologise for the misleading title or agree to amend the listing title or description, and his only offer to resolve was to return the item unused in original packaging (but no Time Machine was offered). I have used some in plant pots instead of gravel but given that I can get gravel for free this is a total waste of £25 :(
