Good day together, I got the clock 2 days ago and I must say the value for money is great, thanks to the App btnotification there is no problem the clock to connect to the mobile phone all the features like SMS reading view calls as well as calls everything works great I have to say the music player is very quiet to sleep but if you want to listening to music as perfect as a little tip I recommend the Sleep mode when you are out to turn off because then the display is clearly brighter.
So I can only recommend if you're not sure whether you need something like this clock, the 40 euro well spent before man spends 200 euros
Conclusion: you can buy
PS have a mini s5 and as mentioned above it works great with the connection
