TLDR The Good: Great battery life. Seemed quite rugged and quality made. Came with glass and plastic screen protectors. Multiple dial faces including the ability to use your own photo. Decent telemetry. Paired easily with my phone. Decent range away from phone. Call quality is ok (see the bad).
The Bad: Very large. Placement of the speaker port makes it hard to hear sounds or conversations. All sound from your phone gets routed to the watch unless you constantly change the settings. Caused skin irritation in my case.
The battery life is great on this watch. I only had to charge it 1 time in the week or 2 I tried it. The quility of the watch seemed above average and like it would hold up to rough handling for the price point The abundant amount of pre-made dials and the ability to add your own photos for a custom dials was a very nice feature, though the photo dial was very basic. I could not tell if the telemetry was accurate or not, but this isn't a medical device, so I took the info provided with a grain of salt.
The deal breakers were:
1) It's size. This thing is huge! I'm no small man, but as photoed, it covered my wrist and then some. This caused me to have to wear it higher than usual on my arm due to hitting the side buttons when I flexed my wrist. This caused settings to get changed and at time the watch to power off on several occasions.
2) The placement of the speaker port is on the bottom of the watch. While this is good for protection from the elements, unless you weirdly contort your wrist, little to no sound can be heard as the opening is covered by your arm.
3) [A personal issue] After wearing the watch for several days I began to develop an irritation. These factors led me to return the watch.
