Well,I do not buy that much hardware because I don't have money but my worst hardware experience is the following:
I bought my HP Photosmart 850 camera.
When i bought it at first,everything
seemed ok,but after a while,the camera's
defect started to be obvious.The
thing was when I made photos in natural light,on the pictures appeared a
dirt,always in the same place.After i figured this out,i went to the shop where
i bought the photo camera and after waiting a week and a half,they brought me
back a SECOND HAND camera,which was scratched all over the place and the
protective cap the camera lens was falling off.Also the camera lens were moving
left and right instead of standing still.I went mad and went again to that shop
to get the camera back.
After waiting TWO Weeks! they gave me another SECOND
HAND camera but this was already at the end of the guaranty.After a week of
using it i realised that this camera too had a big scratch on the camera
lens,but fortunately this is not seen in the photos i make.I also realised that
the camera i last received was 2 year older than my first camera.Shame on you
This is what i got after buying this 700$ photo camera!
