For price close to 1000$ I expected better quality:
-Some places crooked welds
-Numerous scratches made by delivery 
-Two bolts doesn't feet halls. Used drill to adjust them. 
-Installation guide can be better. For instance instead of washer X referred to X1
-U CAN'T swing when bad open. Only when seat back is UP. When down he stay rigid. 
-for easer roof assemble and installation better to use two persons 
-In comparison to cheapest one for 200$, I didn't found something what worth 
  extra almost 800$ 
-Delivery very fast (4 days) But left close to front door without notification. And because 
package very heavy I can't lift it up and move to backyard. So, I opened on front and 
one by one moved parts to the beck of the house.
