I clearly ordered the rubber with blue sponge, but received one with orange sponge. When I contacted the seller and told him that I am not satisfied and that I would not have agreed to the orange sponge if they would have informed me. But the seller only answered that both sponges have the same skills. Nothing more. I answered once more that I am not satisfied with this service, but no reaction from the seller. Therefore I can not recommend this seller.
