Good product... But with the new EU tax, it's too expensive to buy again (€3.60 for the product and +€4 for the new tax)...

I did not receive the item due to aliexpress stupid address change system. since a year as a long term customer i try to correct it. ali is a selfish cheating long term customer company. also it is the fault of the company who sells the item because they do not care if the customer got the item. alis customer service is non existing and not very intelligent. the worst service in the world.
