This is a bit of a gripe and also a cautionary tale about my experience with Asus. Around 26 months ago I bought a TF300T. This worked perfectly for eight months until I started to get problems with the power switch. It became ultra sensitive to movement and often rebooted the tablet merely as the result of vibration. I contacted Asus and they arranged a swift repair. The unit seemed OK until a couple of weeks ago, when the same problem started to manifest itself again. Almost at the same time, the tablet stopped recharging from the keyboard battery and can now only be charged directly from the mains. There is also some sort of black sealant leaking out of the case, around the bottom of the screen. I contacted Asus again and explained all of these problems, but their response was that the unit is now out of its original warranty and they only provide a three-month warranty for any repairs they carry out. As a result, I would have to pay to get the current problems sorted out. Given the fact that their last repair didn't last very long, added to the fact that a second serious fault (the battery recharging) has developed, I am not really inclined to pay out for what will undoubtedly be a fairly costly repair. So it looks as if if my only option is to bin the thing and buy a new tablet. I understand the fact that manufacturers cannot provide never -ending warranties for their products, but in a case like this, where both the manufacturing and repair quality are clearly sub-standard, I would expect Asus to sort the problem out in order to protect their reputation and retain a good customer. As it stands, my next tablet will most definitely not be an Asus. Their motto may be 'Persistent Perfection', but in my experience, they fall well short of that aim.
