A review of Brick, a little box that shuts down your phone

Startup Strategies • 71 implied HN points • 02 Feb 25
đź•ą Technology Product Reviews
  1. The Brick is a device that helps you stop using apps on your phone by locking them down until you tap it again. This makes it harder to scroll through social media mindlessly.
  2. Although it works well to keep you off distracting apps, it's not the cheapest option available. There are free apps like Screen Time that can do something similar.
  3. Some people might prefer making their own version of the Brick with cheap parts instead of buying one. It’s a fun project, but the Brick does its job of reducing screen time effectively.

Kartick’s Blog • 0 implied HN points • 09 Jun 25
đź•ą Technology Product Reviews
  1. The Mercedes EQS SUV is best for people who want to be driven rather than drive themselves. It offers a super comfortable and luxurious experience in the back seat.

All I want for Christmas is…

My Home Office Hacks • 0 implied HN points • 08 Dec 25
đź•ą Technology Product Reviews
  1. A bigger portable monitor can transform remote work and makes small laptop screens feel inadequate for productivity away from home.
  2. The ARZOPA 16.1 is recommended as a great budget portable monitor, with higher-end alternatives like the ViewSonic VX1655-4K, Lenovo ThinkVision M14t Gen2, and InnoView 18.5 also worth considering.

Dr. Vaku Power Bank: Don't Buy

Kartick’s Blog • 0 implied HN points • 22 Feb 26
đź•ą Technology Product Reviews
  1. The power bank frequently stops and restarts charging, making it unreliable for charging two devices at once or for uninterrupted use.
  2. It delivers less power than advertised (often only ~20W or 15W in practice), so it won’t keep a laptop running while you use it and can stress batteries.
  3. Pass-through charging can refill both a drained phone and the bank overnight but is very slow due to a 15W input limit, and the LED/color charge indicators are inconsistent and untrustworthy.

Bose Quietcomfort Ultra Earbuds (Gen 2) Quick Review

Kartick’s Blog • 0 implied HN points • 01 Mar 26
đź•ą Technology Product Reviews
  1. The earbuds deliver outstanding noise cancellation that made airplane white noise disappear, outperforming the AirPods Pro and even some Bose headphones.
  2. Podcasts and voices sound more open and natural with less bass, but sibilance is more noticeable and headphones still sound better overall.
  3. They’re comfortably designed (more so than Bose QC headphones, slightly less than AirPods in short tests), offer multipoint pairing plus USB-C and wireless charging, and have flaky wear-detection; at ₹33K they’re worth it mainly for the noise cancellation and comfort rather than pure audio quality.

  2. AirPods are great for comfort and are useful for casual listening, but they have many connectivity issues and may not be the best choice if you use different devices.
  3. Next time, prioritize comfort over brand and look for wired headphones with USB-C ports for better compatibility with modern devices.

  2. The sound quality is impressive for its size, offering rich and full audio, with strong bass that can enhance movies and music. It outperforms many bigger speakers, making it a great choice for enjoying audio on the go.
  3. While it lacks wired connections and isn't the best for podcasts or as a smart speaker, it excels as a portable audio option. If you prioritize sound quality in a compact design, it's a solid choice.

Kartick’s Blog • 0 implied HN points • 18 Dec 24

  1. The Honda Elevate feels cramped inside despite its big exterior size. The low seating and limited legroom make it uncomfortable for taller drivers.

  3. While it has some good safety features, it misses out on important ones like a multi-collision brake and pretensioners for seat belts, making it less safe than other options.
