DPS series digital input adjustable DC power supply, LED display mobile phone repair power test regulated power supply is designed for car, laboratory, school, production lines and electronic repair designed for use. Voltage stability is high, small ripple factor, has improved the short circuit protection and overcurrent protection.Due to the voltage value is a digital keyboard input, shorten the voltage setting time, completely overcome the traditional potentiometer adjustment poor contact caused by voltage instability phenomenon. The internal power supply containing electronic switch, can conveniently open the output load.

Zero customer service, doesn’t keep time.
Color: 6633: Black band & black dial
Looks nice. Doesn’t work.
This watch does not keep time. You’ll be resetting it constantly, and every time you do, the poorly placed dials end up shifting the date too.
The design is impractical. The buttons and dials get bumped during normal, everyday use, which throws everything off again. The date display is also extremely hard to read, especially if you have even minor vision issues.
The glow feature? Never worked at all.
As for the warranty, don’t count on it. The seller is unreachable, and the listed phone number is out of service. I even purchased an extended warranty, only to find out it’s useless until the original 24-month warranty expires, which you can’t even use in the first place.
Bottom line: this is a good-looking piece of junk. Save your money.

Readability
Color: 6633: Black band & black dial
It is a beautful and heavy watch with interesting dial components. I'm not sure how it can claim to be self-winding, when it requires manual turning every 1-2 days. Biggest disappointment for me is readability. It has no backlighting, so it needs hands with more contrast and more luminescent surface, neither of which it posesses. So, it is practically useless in low light situations... a daytime device at best.
