Yep, this is an unknown brand. Better off with an Anker, Saisho, Matsui or Danone.
Can you use it as an alarm clock? ie turn on at a certain time, and play music or radio.
You have to go to store to get the £49.99 deal from RS (VIP club). Decent Bluetooth speaker with bonus of voice control. Just don't expect it to be the same as a Google home.
How is the broadcast feature hobbled?
I'm happy with mine too, but it doesn't have exactly the same functionality as the Google devices - they keep some features back. I knew that 3rd party speakers didn't have the phone call feature, but was disappointed to find that broadcast doesn't work fully too.
