I have already left a positive feedback when I received and tested the item. The item I purchased was a car radiator which came with 1 year warranty. Now I have noticed that it's leaking from the welds which I consider to be a manufacturing defect which is covered by the warranty. All my attempts to contact the seller have failed, however last night seller has removed a line about warranty in item description. This is a clear indication that seller receives my messages but doesn't want to have anything to do with it, even though it's still under the warranty.
