Trustpilot calculated Grenco Science's score 2.0. The latest review – I placed my order on April 28 and now May 4 I contacted the company asking them where my shipment was after 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.
