Watch body is well built and looks really sharp. Chronograph buttons don't function and subdials on the watch are not functional (as you'd expect from a watch at this price.) The band is lightweight metal and feels cheap although it looks good visually. It's a good purchase if you like the look of the watch.
Watch feels heavy and well made. Band looks good, but is very thin and cheap feeling. Overall watch looks good, but I wish the band had been better made.
Light is well built and a nice size for the pocket. I attached a small metal swivel ring on mine instead of the string wriststrap that it comes with and put it on my key ring so that I could have it handy at all times.
Runtime is around 25~30 minutes using a LiIon rechargeable 16340 880mAh cell. The light is very bright (probably puts out around 150-180 lumens or so), but it does get warmish/hot after around 5 minutes of use.
You can probably get a brighter light for the same price at other retailers. I compared it with my 220 lumen Aurora, and this is definitely a bit dimmer. So FP''s 170 lumen rating is probably about right.
Bought 3 of these and ran them through formatting and write/verify tests. All tests passed, so the data seems to be written and read correctly. I''ve had other Chinese drives that would not reliably store data.
