Be careful with kogan! I've never purchased anything from them but I spent an hour one night on their facebook reading all the complaints on products and especially their service! I quickly googled "kogan service" and this is the first link I looked at and theres plenty more reviews after that!

Hi Ozzy,

I've bought a couple of samsung tab's from kogan over the past couple of years

1 x 10 inch

2 x 7 inch

all worked great have had no problems with the goods or Kogan.

However, on the Interweb, people are more prone to write negative things

about their online experiences, than positive things.

Cheers

Norty

P.S. I am in no way affiliated with Kogan other than being an occasional customer.

If you're on facebook check out the customer comments on any of the posts from kogan, all trying to chase up faulty goods or customers waiting 3-4 weeks for a product on a 5 day delivery service. I'm on there right now its quite entertaining haha
