(37)Since in the case of distance sales, the consumer is not able to see the goods before concluding the contract, he should have a right of withdrawal. For the same reason, the consumer should be allowed to test and inspect the goods he has bought to the extent necessary to establish the nature, characteristics and the functioning of the goods. Concerning off-premises contracts, the consumer should have the right of withdrawal because of the potential surprise element and/or psychological pressure. Withdrawal from the contract should terminate the obligation of the contracting parties to perform the contract.
