See, the word clone implies that it's a similar product, but these are not similar except for certain looks of the proudct.
In terms of construction, functionality, quality, and warranty, these knockoffs can't be compared.
For example some big windows lover at my company bought an iPhone knockoff (because the knockoff lists "more features"). It's made of cheap plastic, uses stylus instead of touch and it's dead after 6 weeks. LOL. You get what you paid for.
