Nice concept
The concept is really good. I would have given it  5 stars but not all the parts have a smooth connection.  I don't know if it will change in time or if it's a defect. I will say its important to have all the pieces securely in the elastic.  When I opened the box the sharp attachment fell out  & hit my leg.  I make sure it is zipped all the way & that problem seems to be fixed.
