A grip tester that held up against a professional-grade unit in at least one side-by-side comparison, worth it for tracking grip strength progress over time rather than as a single fixed resistance trainer.

Overview
A digital hand dynamometer that measures grip strength up to 400 lb or 180 kg in 0.2 lb increments, paired with an adjustable gripper offering 11 to 132 lb of resistance and storage for 19 user profiles.
The measurement side and the training side are two different functions worth understanding separately: the dynamometer reads grip force digitally, while the attached gripper is a separate adjustable-resistance trainer, which appears to be the source of at least one reviewer's confusion between a reading and the gripper's resistance setting. Another buyer who compared readings against a physical therapist's professional-grade unit found the numbers held up.
- Measures up to 400 lb / 180 kg
- 0.2 lb / 0.1 kg measurement precision
- Adjustable gripper, 11 to 132 lb resistance
- Stores 19 user profiles with history
Who it's for
Suits physical therapists, athletic trainers, and home users tracking grip strength over time, including for rehab after an injury. Less suited to anyone expecting the displayed grip-strength reading to match the gripper's resistance setting, since these measure different things.
What buyers say
From Amazon customer reviews.
Buyers who tracked grip strength for rehab or training said the readings felt consistent, with one comparing it directly to a physical therapist's professional-grade dynamometer and finding it held up. Complaints included a unit that shipped with a piece of paper stuck inside the display, which the seller offered to resolve with a refund, and one reviewer who was unhappy that a grip-strength reading did not match the gripper's rated resistance number, though these are two separate measurements on the device.

Performance notes
A strain sensor reads grip force to within 0.2 lb or 0.1 kg and displays it alongside a stored user profile, letting you compare against a previous test for the same person. The separate adjustable gripper runs from 11 to 132 lb of resistance for training, independent of what the dynamometer measures. A mechanical counter inside means it runs without charging or batteries.
