This light string is an absolute impudence!
It smells extremely unpleasant, absolutely useless for interiors, unless you want to bring toxic fumes into the apartment. I doubt that this product has a CE approval and that it must be sold at all in Germany.
The trader RPGT received in no way limited to the complaint. The return costs for this is probably not even marketable product were not reimbursed. I received an e-mail in English and German machine translation.
It will be sent from Germany, the dealer is located, however, lt. Contacts in China. Untrustworthy.
