Very disappointed Very disappointed in the whole process. First you sent the wrong item. Then told me the right item would arrive in two days and when I called it hadn't even been sent yet. Then they told me I would not be able to get it by Christmas and the only thing that they could do is refund my money. I will probably never use your company again and never recommend you company to anyone.

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. The customer service person on the phone just kept repeating that delivery dates can't be guaranteed after the item is shipped and that there was no way to cancel the order or change shipping speed. I won't be using this company again - there are plenty of other places that DO ship and have items arrive on the date specified.

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. Rather than take care of the issue Scientific screwed around, I had to put the purchase in dispurpte and find another simular item. 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.

Products look good online Not too happy with the items i purchased, they look a lot better online than they do in life. The moon shoes are not worth even half what I paid for them, very cheaply made and the same goes for the Newton's cradle. Unfortunately i cannot send them back as they were gifts. I won't purchase from this site again though. They were delivered according to site specifications and this is the 2 star rating.

Received damaged box with item missing. Ordered on 1/30/17. Received on 2/4/17. Box was damaged and item #3153162 was missing but other 2 items were still in box. I called right away, sent pictures of the box and was told another would be sent right away. Never received it.
