I (still) like it
Color: B Black
Looks solid, considering it is lightweight plastic. Very large. I have a large wrist and still I needed to remove 3 links. Link removal took a while to figure out. Needed the video (QR code in box), a bright light and magnifying glasses (to see the inside arrows and tiny pins). It seems to keep good time, though the hands are slightly off -- for example, at 3 o'clock, the hour hand is a bit after 3, not right on 3. At 6:15, it seems it will be 7 very soon. Maybe it will make me early for a change LOL. Mostly I just really need a watch to tell the time, without having to pull out my phone. This does the job, with a bit of style and a touch of irony. Update, after 5 months of daily use: The watch still looks good and the timepiece still functions. Sadly, a small piece of plastic broke off the watch band, where the pin connects, so the band will not stay together. It is a larger piece of the band, near the dial, so there are not extra links of that size to repair it. There does not appear to be a warranty. Up to this point, I have received several compliments on the watch. I agree that the contrast is rather eye-catching. I may buy a second one and use the first watch for parts.

Cheap dial
Color: E Gold Black
As a whole it's a quartz plastic watch for under $20...I'm disappointed in the poor looking dial quality. The case seems fine for a plastic watch, it's no Swatch but not a bad case. Shame the dial looks so cheap, it may have passed at a glance as a nice watch otherwise.

NOT WORTH IT
Color: E All Black
Not worth the money in my opinion. Very light weight. Almost like wearing a child's watch. Cheaply made.
