Overview
The NIYIKOW NYK-2PB is an adjustable hand grip strengthener with resistance from 22 to 132 pounds (10 to 60 kg), aimed at building hand, wrist and forearm strength in a pocket-sized tool. It suits anyone wanting to train grip incrementally without buying multiple fixed-resistance grippers.
- Adjustable resistance from 10 kg to 60 kg
- Non-slip handle covering
- Reinforced metal alloy and heavy-duty plastic build
- Pocket-sized for carrying anywhere
Who it's for
Good for people who want one gripper that scales from light to demanding resistance, including musicians, climbers and anyone rebuilding grip strength. Less ideal for someone who prefers the fixed, wider handle spacing of a traditional single-resistance gripper.
What buyers say
From Amazon customer reviews.
Buyers consistently praised the adjustable resistance range and called the build sturdy for the price, with several noting the non-slip handles feel secure through repeated use. A couple of reviewers raised concerns worth flagging: one questioned whether the spring might wear out over time without having experienced a failure, and another pointed out that the handle spacing narrows as resistance rises, since the coil extends and puts the grips closer together than a typical hand span, which affects squeeze feel for larger hands.
Strengths and trade-offs
Drawn from this product's published specifications.
- Adjustable range from 22 to 132 lbs (10-60 kg)
- Non-slip handle covering reviewers describe as secure
- Compact enough to carry in a bag or pocket
- Handle spacing narrows as resistance increases
- One reviewer questioned spring longevity over time
Performance notes
Resistance is set by turning the adjustment mechanism between 10 and 60 kg, and reviewers describe the tension as firm and progressive rather than jumping suddenly between levels. The handles are covered in a non-slip material that multiple reviewers called secure during use. One reviewer flagged that as resistance increases, the coil extends and the handles spread to roughly 5.5 inches apart, narrower than the average 7.5-inch hand span, so squeeze range shrinks as load goes up compared to fixed-width grippers.
