I see alot of hate towards HSN here, some which is true, no doubt. The point is that they are not perfect, far from perfect actually. But they are not forcing anyone to buy anything from them. All of you should know that they did announce about the warranty issue before starting it (on their facebook page and website afaik), now it's your choice if you want to buy from HSN or anyone else. Though, I agree that the info present on their product pages can sometimes be misleading, that's mainly because they copy paste from official pages of the respective vendor.
I can only write about my own experience here which is only positive. Products I've bought from them include HTC EVO 3D, 2x HTC Chacha, Nexus S and Nexus 7. Not even once did I face any issue regarding the product they sent. However, I still believe they shouldn't use BlueEx for shipping as they take alot of time shipping to smaller cities.
And no, neither am I partners with them nor do they pay me to write this post.
