I was sold this item only to learn, after opening the corresponding Web site necessary for eMarker function, that Sony was terminating the corresponding Web service in 45 days!!A great idea but no support.

Negative

We bought this for my 4 year old son for Christmas and I am very sorry we spent our money on it. Putting it together was not fun, but the real disappointment came when it was done and you see what it is. I think it is unrealistic to think that most people will want to or ever allow this toy to be STUCK to the wall with an adhesive (it says not to leave it stuck there for long periods of time - you must remove it from the wall after playing with it - which means this flimsy piece of plastic is now laying on the floor). After playing with it for 10 minutes, the elevator gets stuck. The top keeps falling off, everytime I turn around my son is whining that this came apart or that came apart. I assume I will be super gluing it before long. I feel ripped off as a consumer. Buyer Beware!

Ex Output:
Negative


Ex Input:
The content does not simulate the actual USMLE and there are so many nagatively phrased questions and also, most of the questions are never asked as for as my step1 experience goes.
