Overview

An adjustable hand gripper with resistance claimed from 22 to 330 lb, set by turning a dial rather than swapping springs, paired with a mechanical rep counter that clicks with each squeeze and needs no battery.

The counter is the standout feature, and reviewers largely liked the audible click for tracking sets, though more than one noted it is awkward to reset to zero. Several buyers also questioned whether the top-end resistance genuinely reaches 330 lb, since their grip strength measured on other testers topped out well below that figure.

  • Claimed 22-330 lb adjustable resistance range
  • Built-in mechanical rep counter, no battery needed
  • Reinforced metal pins and ABS housing
  • Oversized TPE rubber handle

Who it's for

Works for people building forearm and hand strength for climbing, playing an instrument, or general fitness, and for anyone doing hand therapy for carpal tunnel or post-surgery rehab. Less suited to smaller hands, since the handle and grip split were described as large and uncomfortable at full tension.

What buyers say

From Amazon customer reviews.

The mechanical click counter was the most praised detail, though several buyers found it awkward to reset between sets. A few reviewers doubted the advertised 330 lb top end after testing their own grip strength against it, and one reported the internal spring breaking within a month of regular use, while others called it comfortable enough for daily casual use at its price.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Rep counter clicks reliably during use
  • Adjustable resistance suits a range of strength levels
  • Comfortable oversized handle for extended sessions
  • Low price relative to comparable grippers
What to check first
  • Actual top-end resistance likely below the advertised 330 lb
  • Counter is fiddly to reset to zero
  • Handle size and grip split awkward for smaller hands
  • One reviewer had the spring break within a month

Performance notes

Resistance is set with the adjustment dial rather than fixed springs, so the same unit can go lighter for warm-ups or higher for a harder squeeze, though reviewers who tested it against hand dynamometers found the true resistance fell short of the advertised 330 lb ceiling. The oversized rubber handle spreads the load across the palm, but a few users found the split grip shape awkward at full tension.
