What reviewers say

Distilled from the video reviewers — the score, what they praise, where they push back.?

Forerunner 255
across 5 reviews
4.5/5
mixed
Reviewers praise
  • Multi-band GPS accuracy stands out, especially in challenging environments with tall buildings
  • Full triathlon capabilities with open-water swimming and cycling power meter support now included
  • Fourth-generation optical heart rate sensor performs well across activities
Reviewers push back
  • Music version limited to four gigabytes of storage versus much more on higher-end models
  • Optical heart rate sensor accuracy varies by user—skin tone, tattoos, and wrist anatomy affect readings
  • Lacks Climb Pro feature found on more expensive models
Reviewers agree the Forerunner 255 delivers exceptional value by bringing premium features—multi-band GPS, triathlon support, barometric altimeter, and HRV tracking—down to a mid-tier price, making it a standout upgrade from the 245.
— best for: Runners and triathletes wanting advanced training metrics, accurate GPS, and comprehensive multi-sport tracking without paying for a flagship watch.
Galaxy Watch 8
across 4 reviews
3.5/5
divided
Reviewers praise
  • Thin, flush profile and soft silicone band make it noticeably comfortable for all-day and sleep wear
  • Bright OLED display — boosted to 3,000 nits — reads well in strong sunlight
  • Stainless steel frame feels durable and shows no scratches in extended testing
Reviewers push back
  • Battery life with always-on display active lands around a day, requiring daily charging for heavier users
  • The squircle case design is polarising and leaves unused visual real estate in the corners
  • Body composition measurement is awkward on smaller wrists due to the flush, low-profile chassis
The Galaxy Watch 8 is a well-built, comfortable smartwatch with a capable display and solid health tracking, held back mainly by battery life that demands daily charging for heavier users.
— best for: Android users who want a slim, comfortable daily smartwatch with solid health monitoring, a sharp display, and tight Samsung Health integration.

Battery stamina divides reviewers: one found nearly two days possible with always-on display off and moderate use, while another characterised it as average and unremarkable compared to dedicated fitness watches

Are you tech challenged? Want a simple way to track activity right "out of the box"? This watch is IT! I LOVE the design...the graphics are BRIGHT AND LARGE enough to read at an arms length. The function buttons respond instantly! My Venu Sq face would fog up after every run making it hard to use functions. I have been running in 94%+ humidity and have had NO FOG!!

I was pleasantly surprised by the elegant and minimalist design – it looks luxurious, yet the watch is lightweight and very comfortable to wear. The strap is soft and stays firmly in place, even during workouts. Display is bright, crisp, and incredibly smooth – even outdoors in direct sunlight. The interface is intuitive, making it easy to navigate between features and customize settings to fit my Ingi · Samsung
