Good hardware but week software!
Advantages: Hardware: is strong and good enought for this value, good GSM network signal strenght, nice design and display.
Limitations: Harware: week WIFI signal (even if you are close to AP or Router), even if you didn't check the option to use powersaveing mode the WIFI turn OFF every time you go in sleep mode (in this way you never get any messages till you come out from sleep mode and check the time or something and take 20-30 seconds every time to reconnect to WIFI network), if WIFI on your battery drain fast (maybe the reason to disableing WIFI even if you don't want it on sleep mode), Software: all the clock design's and also all the softwares witch are from manufacturer has very slow (week) internet connection, and this way you have to wait some more time to donwload them (playstore working fast), Skype from the manufacturer is not working ... same with Whatsapp, No forum or support for software found on manufacturers webpage. I hope that the manufacturer will make open source the drivers and or make some optimized ROM for these great Hardware watche's.
