Tker Himalayan Natural Salt cooking Blocks Crystal Plate for BBQ grilling

Wanted to try these for some time and decided to purchase and give it a go.  I have grilled Asparagus which came out just perfect twice.  Also tried cooking burgers on the and some sausage.  Overall the food tasted very good and the salt blocks cleaned up OK although it took more than a rinse off.  I noticed on my 4th grilling experience using the blocks developed cracking in them and are not holding up as I expected.  With that being said, they seem fine for grilling veggies.  Not sure I would purchase any again from anyone.   3 Stars for the product 5 stars for the seller!
