Hello there, I am about to purchase a Harmony 900 Remote from the USA as i have a friend who has traveled there and is there at the moment. Could someone please assist me on the following: On the Harmony 900 Spec page Logitech > Remotes > Harmony Remotes > HarmonyÂ® 900 it mentions that the Harmony 900 comes with 4 IR transmitters (Mini Blasters) whereas on the US store websites such as Best Buy, Frys, Circuit City etc it mentions 2 IR Transmitters (Mini Blasters) I also had a look at CNET's review Logitech Harmony 900 Remote Control reviews - CNET Reviews and here too it mentions 2 IR Transmitters and not 4. Please could you advise me if there has been a update to this remote and if apart from the blasters has the issue with regards to poor RF range also been improved. I am concerned that it is quite expensive for a remote but i am prepared to pay for it, but i don't want to then learn that i bought a remote that has been upgraded as far as the hardware (and firmware) goes. Secondly does anyone know if the AC Power Adaptors (in the USA) supplied for the remote recharging stand and the RF receiver are multi voltage? i.e. will they work on both 110 AC an 240AC? As where i am, we have 240 volts AC. I was thinking of asking him to buy it from Best Buy or Frys....and i want to be sure i am getting the latest version if indeed there has been any updates. Thank you.
