Product Quality: 4.5
Instuction Manul: 3 manual is not clear in many steps and images are not showing properly hence leaving lot of confusion and rework 
Ease of fixing: 2, it took me 8 hrs and so difficult to fix the things and bad part is they didn't include required tools to assembled 
P.S: When 100$ items also has required tools to assemble, this don't have thought price is around 300$ and we have to use different tools to fix different nuts and bolts
