Blue LED Digital Dual Air Pressure Gauge with Electrical Sensor

first impression, i was skeptical because i've had bad luck with digital gauges in the past, but this one from topfactory has been reliable. as a chef who also tinkers with cars and tools in my spare time, i appreciate things that just work without fuss. it's helped me catch low pressures before they became real problems, like avoiding a flat tire on a road trip. compared to the old dial gauges, it's a huge improvement in accuracy and convenience. i've been using it for a couple of months now, and it's held up well with regular use. it's not perfect, but for most folks, it's a solid choice that makes life easier. i'd recommend it with a few caveats, like maybe adding a dimmer for the light.
- Pros: the blue screen is extremely clear and easy to read even in my dimly lit garage, which saved me a few times when checking tire pressures at night. i like that it shows two different pressures at once, so i can keep an eye on my car tires and my air tools without switching between gadgets. it hooked up easily to my existing setup with no extra wiring needed, making it a straightforward upgrade.
- Cons: it could be wrong, but i feel the display might be a bit too bright in complete darkness, and the unit is a bit small, so mounting it securely took some extra effort. for the price, i expected it to be a bit more rugged, as it feels a bit plasticky compared to some other gauges i've used.
