I placed my order on April 28 and now May 4 I contacted the company asking them where my shipment wasafter paying extra for UPS and they told me that I will expect it to arrive in another 10 to 14 days which is completely inappropriate because nowhere on the website does it say anything about delays in shipping it only says delays in customer service and they do not pick up the phone I read this company a one because they did not even have the courtesy to email their customers of the product that I already paid for to advise me about their delay in shipping

It could be !

Reviewed on 2016-03-23T09:43:26.422

It could be an extraordinary product , but talking about gpen there is a problem : the smell of plastic.After tried different pen and all presented the same smell, I opened the pen to understend what is smelling so much . The fault is of a kind of glue wich is used for the inside component . Only one pen ( of 5 tried ) was without this glue and only one pen was not smelling of burn plastic ( the glue was smelling of burn plastic when in use ) .
