The fitbit blaze you listed does NOT have the ability to reply to txts or messeges in any way though . You can veiw your txts on it only . It does not have built in GPS ether . The fitbit charge Hr does have gps but has a monochrome screen and costs a little more . I have the Gear s 2 3 g . It has amoled full color screen and built in GPS , can reply to txts or any messaging app right on the watch too . The Bluetooth only is available at best buy certified refurb for $ 160 . The gear s 3 being the best but is above the price you mentioned . The fitbits are nice but they are a bit more fitness tracker than smart watch . Not having gps only limits the device from maping runs or activities without your phone which also might not matter to you .
