Well, this is my first time try to write a review and I am super frustrated (yet surprised) by (1) how bad a product can be, and (2) how a relatively high review this product has received already. 
We just moved in and we bought lots of new things need to be assembled at home. Most of them a none American companies, and although I do not like to admit but they are MCUH MORE better than this one (which I proudly purchased as an American product)!    
None of the holes are aligned, none of the cuts are perfect, quality in the lowest possible. 

I assembled it twice and in both cases with a single touch it collapsed! and do not mistaken, I am a handy man and I already did many this kind. 
I was thinking at some point to use it as a seismograph to record negligible seismic motions that  even a human in rest may not feel it. 
I will try to return it, but even in that case, I am super disappointment to see such a product in the USA!!!
