Scienlodic is NOT US based company
The company pretends to be in the USA but its not. That is the reason why their shipping takes 2 to 3 weeks. They answer your email, night time in the US which is day time in China. Chinese characters all of a sudden appeared in the email thread. Also, they DO NOT have a phone number for customer service. Its very fishy. They also create their own positive reviews online. Scienlodic is not based here in the USA as they try to impress. Their website is deceptive.
