Do You Really Need an Expensive Fitness Band?

When I started hitting the gym, I wanted something to track my heart rate during workouts. But Mi Bands cost $30~40 and Samsung Galaxy Fits run close to $80. All I needed was basic heart rate and step counting — did I really need to spend that much? So I went looking on AliExpress for the cheapest functional smart band I could find.

How long does shipping take and what's included?

Arrived in about two weeks. Small box containing the band itself, a charging cable, and a basic manual. Packaging was simple but everything came intact. The band is lightweight, and it was protected in a small plastic case. Charging works by detaching the band unit from the strap and plugging it directly into a USB charger.

How does it perform in everyday use?

The screen is a small color display — roughly 0.96 inches — which is impressive at this price point. Brightness is fine indoors but struggles under direct sunlight. Touch responsiveness isn't as smooth as premium bands, but it handles basic navigation without issues.

Heart rate monitoring kicks in automatically when worn. I compared it against my Xiaomi band and found a variance of about 5~10 BPM. It's not a medical device, so think of it as a rough trend tracker rather than precise measurement. Step counting is similarly approximate — not 100% accurate, but good enough to gauge daily activity levels.

The sleep tracking feature exists and does a reasonable job detecting bedtime and wake-up times. Deep vs. light sleep classification should be taken with a grain of salt.

Does it connect reliably to your phone?

Install the companion app and pair via Bluetooth. Getting text and app notifications as vibrations on the band is surprisingly handy, especially during workouts when you don't want to check your phone constantly. The app UI is a bit rough around the edges, and some translations are awkward, but it gets the job done.

Battery life is solid — about 5~7 days on a full charge. No daily charging hassle, which is a genuine plus at this price.

How does the price compare to competitors?

Source Price
AliExpress (sale) $4.58
AliExpress (original) $4.79
Amazon (similar) $12~25
Walmart (similar) $10~20

At under $5, it's a fraction of what comparable bands cost on Amazon. Even the cheapest Amazon options are typically 2~3x more expensive.

Pros and Cons

Pros

  • Absurdly cheap at $4.58
  • Heart rate, blood pressure, sleep, and step tracking
  • Color display at this price point
  • Daily waterproof rating
  • 5~7 day battery life
  • Phone notification support
  • 3,559+ units sold — reasonably proven

Cons

  • Measurement accuracy lags behind premium bands
  • App interface is clunky
  • 78.1% positive rating — not stellar
  • Display hard to read in bright sunlight
  • Build quality is plastic-y (expected at this price)

Who should consider buying this fitness band?

  • People who want basic workout tracking without spending much
  • First-time smart band users who want to test the waters
  • Anyone who needs a backup/beater band they won't cry over losing
  • Budget-first shoppers
  • Gym-goers who just want a quick heart rate check mid-workout

The Bottom Line

For $4.58, you really can't complain. Don't expect Apple Watch-level quality, but for "check my heart rate at the gym and get notifications on my wrist," it delivers. The 78.1% positive rating is a bit of a yellow flag, but given the price, it's understandable. If you want a no-risk way to try a smart band, this is about as low-stakes as it gets.
