The first one of these I tried to buy never turned up from Amazon, the second was not really worth the wait either.
When it works, this item can be a useful toy. If you intend to use with home automation, eg Harmony then again, useful.
BUT > If you intend to try and use with the ByeBye Standby website forget it ! The website is unreliable - it goes off line for periods with no explaination and even having sent a series of emails sent to the support team, there is no fix in sight. You can still use the remotes and send commands direct from your own app, but hardly the point when this is supposed to be an internet enabled device. I have not tried the Premium services, but if the free website is anything to go by then I'd be surprised if it works.
I'm regretting the purchase.
