870i (Gen 2) vs T618
How these two compare on everything we measure — where the AIs rank them, what reviewers and buyers say, and how they price. The differences are the point — they decide which one is yours.

Built from what 2 AI models (Gemini · ChatGPT) recommend for real buyer questions, layered with reviewer test summaries, Google buyer ratings, street prices and press. The short answer and verdict are derived from where those signals diverge — not written by hand for either product.

What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Large running surface measures 20 by 60 inches with 2.75-inch diameter rollers that reduce noise and extend belt life
- Rebound cushioning system reduces joint impact during workouts
- Twenty-six workout programs covering endurance, weight loss, and interval training with fitness scoring
Reviewers push back
- Frame lacks the sturdiness needed for sustained running—the machine shakes noticeably at higher speeds
- Wireless chest strap heart rate monitor works inconsistently across users
- Cannot program custom workouts—only preset programs available, requiring manual button adjustments
A mid-range folding treadmill that serves walkers and light runners adequately but reveals its construction limits under serious running loads.
One reviewer found the heart rate chest strap failed completely for him while working for others in his household
