Arrived 2 days before the earliest expected date.
Seems ok, connected to my phone well. The manual gives a link to the apk file (for android) and it's pretty straight forward.
The manual does come in chinese, but there's also an english section which, whilst not Hemingway, does make sense and is easy to follow.
The capacitive screen is rather good, haven't found any dead spots.
Comes charged, though likely low like mine was.
There are a few downsides, whilst you can play music from the watch and change the volume for it, you can't change the volume of music when you're listening to it on your phone. But, it's like £30, it's not that big of a deal.
The straps a bit pants, but seems rugged enough. It's rubber, but again, £30.
The plug included is an american plug (I think) not a UK one, but that's really not a problem. If you have a smart phone, and it's likely you do considering you're looking at this watch, you'll likely have a 5v USB charger laying around which will work just fine.
Really, I'm quite impressed with it. I'd definitely recommend it. It's not a pebble, or whatever the latest apple watch is called, but for the price it's well worth it.
