With some hesitation, we bought two of these desks.  As it turns out, all my worries were for overcome.  Here's what I was worried about:
--> shipping a glass desk ... no problems!  Well packaged and arrived in perfect shape.
--> putting together a desk ... no problems!  Instructions, although mostly pictures, were clear and easy to follow
--> the stability of a put-together desk ... no problems!  The design of the desk makes it stable and easy to work on.  No wobble or sway!
--> would it be cheap and easy to break? NO :)  Buying these two desks for kids to do their homework made me worry that they would treat the desk rough and that the glass would become nothing but a hazard.  The glass is thick and there have been no issues. 
The pull out try isn't really being used - kids are using tablets for homework.  
Very happy and satisfied with our purchase.  (And keeping fingers crossed that grades go up )
