At a Glance

Design & Build Quality

The Acaia Lunar has that premium coffee shop aesthetic—sleek, minimalist, and built like a tank. The aluminum body feels substantial and can handle daily abuse from busy baristas. I’ve seen these things take a beating and keep working perfectly. The surface resists scratches and coffee spills, which you’ll appreciate after your first early-morning disaster.

The Timemore Black Mirror takes a different approach with its more compact plastic build. It’s lighter and takes up less counter space, which is great if you’re working with a tiny kitchen. The plastic doesn’t feel cheap, but it definitely doesn’t have that premium heft of the Lunar. Still perfectly adequate for home use, just don’t expect it to feel like a $200 scale.

Performance

Both scales nail the basics—2,000-gram capacity and 0.1-gram accuracy. The Lunar responds faster and settles on readings almost instantly, which matters when you’re pulling shots back-to-back. I’ve noticed the difference during busy brewing sessions.

If you’re looking for a great entry-level option, consider our post on the best budget espresso machine. Some users report occasional hiccups with reading stability, but honestly, for home use, it’s more than adequate. Unless you’re grinding and brewing for a crowd, you probably won’t notice the difference.

Noise Levels

Both scales are practically silent. No annoying beeps or buzzing to wake up the house during your 6 AM coffee ritual. This one surprised me—even cheap kitchen scales usually make some noise, but both of these are whisper-quiet.

Filter/Maintenance Costs

Zero ongoing costs here, which is refreshing. Just wipe them down occasionally and you’re good to go. The Lunar’s protective cover is a nice touch, but both scales are easy to keep clean. No filters to replace or special maintenance required.

Smart Features

Here’s where the price difference really shows. For more tips on perfecting your espresso, read our article on how to dial in espresso. I actually use it, which says something since most coffee apps are terrible.

The Timemore app exists, but it’s pretty basic. Bluetooth works fine, but the features feel like an afterthought. If you just want to see your weight on your phone screen, it’ll do that. If you want actual brewing insights, stick with the Lunar.

Price & Value

The Lunar at $199 is expensive for a scale. Full stop. But if you’re serious about coffee or work as a barista, it’s worth every penny. If you’re considering investing in espresso equipment, our post on espresso machine buying guide is a must-read.

The Black Mirror at $99 is honestly the better value for most people. You get 90% of the performance at half the price. Unless you need the Lunar’s speed and app features, save your money and buy better coffee beans instead.
