This is a very poor company to buy from... So, I purchased an item that was reviewed by Matt Granit...I bought it for my daughters birthday present and so she could use it for her classes. Scientific said it was shipped, we did not receive it...and they couldn't prove delivery.

They don't make it easy to buy from, they don't make it easy to work with...in short they don't care about the Customer.

delivery date subject to change without notice I ordered a Christmas gift on the 16th and delivery date was set to be before Dec. 23. On Dec. 20 I was sent the tracking number - the next day the tracking showed a delivery date of Dec. 27.
