Product review (1 stars): Defect Product
Ordered this in October 2017 and just used it on February 2018...  Then I realized it is a defect.  Return window is now closed so I went to Home Dept and bought another one.  Will cancel the subscription program of this product and use Home Dept's subscription program since they got longer return policy.  Things like this is that you won't know it's a defect until you actually used it.  Will not try to stack it in the house anymore (actually I had another one from amazon and that turned out to be defect as well).
