Very Useful for Grip Strength
Well made, highly useful hand grip dynamometer promptly delivered. For those whose hand strength might be in question, this device can quantify present strength and also provides a grip building unit to increase grip power should it be below what it should be.

Gym-Grade Precision at Home!
As a casual weightlifter and dad of two rowdy kids, I never thought I’d geek out over a grip strength tester—until the dynamometer turned my garage gym into a legit training lab. I bought this on a whim during Prime Day, skeptical it’d survive my chaotic household. Six months later? It’s survived juice spills, toddler tantrums, and my obsessive data tracking—and still works like Day 1. Here’s why this gadget became my fitness secret weapon. First Impressions: Built Like a Nokia Phone When the box arrived, my kids tried commandeering it for a “sci-fi robot arm.” But the moment I gripped the industrial aluminum handle (swaddled in sweat-proof rubber), they knew this wasn’t a toy. The LCD screen lit up like a mini Times Square billboard—0.0 lbs staring back, daring me to squeeze. Setup took 10 seconds: Pop in the included AAA batteries, adjust the grip width (I’m 6’1” with bear paws—3.5” setting fit perfectly), and crush away. First test: 68 lbs right hand, 61 lbs left. My 9-year-old yelled, “Dad, you’re weaker than Mom!” (Wife hit 72 lbs. Cue midlife crisis.) Real-World Wins: From Dad Bod to Deadlift God 1. Gym Breakthroughs I’d plateaued at 315-lb deadlifts for months. The dynamometer exposed my grip as the weak link—I could only sustain 55 lbs for 10 seconds. After 8 weeks of grip-specific training (tracked daily), I hit 85 lbs grip strength and finally pulled 365 lbs. My gym buddy bought one immediately. 2. Parenting Hacks Turned grip tests into a game: Kids earn screen time by beating their last score (their tiny hands use the 1.6” narrow setting). Discovered my son’s baseball throw accuracy correlates with left-hand grip strength—coach now uses our data for drills. Why It Beats Cheap Alternatives Tested a $29 Amazon “fitness grip tester” for comparison: Plastic vs. Tank: Competitor cracked when I sneezed mid-squeeze (yes, really). Guesswork vs. Precision: Cheaper model fluctuated ±15% between tests; this stays within 2%. One-Size-Fiasco: The budget option’s fixed grip strained my wife’s smaller hands—no adjustability. Unexpected Life Upgrades BBQ Cred: Friends now demand grip showdowns instead of cornhole. Prize: Last slice of brisket. Workplace Clout: Brought it to the office—HR uses it for “wellness challenges.” My 92-lb score is office lore. Final Verdict For under $80, this gadget delivered: Avoider’s cure for $120/month gym fees (home grip training = 3x weekly sessions) Marriage therapy via grip rivalries (spousal PRs > couples’ yoga) Proof that dads can still out-grip teens (until mine hit puberty) If you want to turn “I think I’m getting stronger” into cold, hard data—or just shut up your cocky kid—this dynamometer’s your MVP. Now excuse me while I go reclaim my title from the Mrs…

Pretty cool
I bought this for my weightlifter-son as a Christmas present. Both I and my father are as impressed with it as my son and his workout buddy friends are. It's easy to use; there's no need to tare it out or reset it if you want to test your grip strength repeatedly. It's adjustable; my son's hands are slightly bigger than mine, and for me to give it a proper squeeze, it's just a matter of spinning the inset adjustment dial to achieve the proper distance to measure my grip strength. It has comparative settings; I was able to find out I have the grip strength of the average 17 year old young man - not bad for a guy approaching 50 (my father, approaching 80, had approximately the same grip strength, which is even more impressive). Oh, and the price is right, too. If you're training your grip, it even comes with an exercise handgrip to build up its strength, and, though I haven't actually tried it, my son said it's well built, as well. Like I say, pretty cool, and definitely worth every penny spent.

Numbers Don’t Lie!
Let’s talk about grip truths. For years, I thought my handshake was firm – until I tried arm-wrestling my 12-year-old niece and lost. Mortifying? Absolutely. As a physical therapy patient recovering from a wrist fracture, I needed objective data, not guesswork. My therapist recommended this grip dynamometer, and suddenly, I’m not just tracking progress – I’m obsessed with the cold, hard metrics of my own comeback. The “Before” Wake-Up Call: Post-surgery, my right hand felt like a deflated balloon. My PT would say, “Squeeze harder!” but how much harder? When I borrowed a hospital-grade dynamometer (think: clunky 90s gadget), it felt like gripping a brick with a calculator taped on. Enter this sleek little device – it’s like the Apple Watch of grip measurement. First Squeeze Reality Check: Unboxing it felt like holding a sci-fi remote. The ergonomic design molded to my palm, no awkward wrist angles. I tapped the touchscreen (yes, a touchscreen!), set it to kg mode (because metric feels fancier), and squeezed. Dominant hand: 18.3 kg. Non-dominant: 11.7 kg. The numbers glared at me like a bad report card. But the instant feedback lit a fire – finally, something tangible to beat! Why It’s My Rehab MVP: Precision Therapy: My PT customized exercises based on weekly data trends. No more vague “push until it burns.” Gamified Recovery: Set a goal to hit 25 kg in 8 weeks? The app’s progress graph turned rehab into a RPG quest. Level up! Portable Motivation: Tossed it in my gym bag. Now I test my grip pre-workout – watching numbers climb is better than pre-workout powder. Unexpected Wins: Workplace Cred: Used it at a team meeting to “settle” a debate about keyboard fatigue. Now I’m the office ergonomics guru. Grandparent Flex: Showed my grandkids how Grandpa’s grip beats their Nintendo Joy-Con drift. Their awe? Priceless. Data-Driven Zen: Instead of obsessing over vague “weakness,” I celebrate micro-gains – 0.5 kg increase? Cue a victory smoothie! Pro Tips for Nerds & Newbies: Consistency Is Key: Measure same time daily (I do post-coffee, pre-email chaos). Grip Angles Matter: Rotate the device 45 degrees for forearm-specific tracking (my PT’s secret sauce). Sync Savvy: The app’s cloud backup saved me after a phone meltdown. Data survives all! Real-World Superpowers: Grocery Bag Test: Went from struggling with 3 kg bags to confidently hauling 8 kg of farmers’ market loot. Rock Climbing Redemption: Pre-injury, I dangled like a piñata. Now I track grip symmetry to prevent re-injury. Coffee Mastery: My pour-over game leveled up – steady hands = barista-level precision. Final Verdict: This isn’t a gadget – it’s a mirror for your muscles. Whether you’re an athlete optimizing performance, a post-op patient chasing milestones, or just someone who wants to shut down “weak handshake” jokes forever, this tool turns invisible effort into visible triumph. My grip’s now at 27.6 kg (flex emoji), but the real win? Walking into life’s tug-of-wars knowing exactly what I’m made of. Literally.

Ahahaha... Idéal pour savoir si on est un dieu Grec ^_^
Nan c'est marrant comme appareil car ça devient littéralement un jeu entre ami(e)s :-D Si quelqu'un fait un score plus élevé c'est direct "ouais je suis plus fort que ta gonflette!" :-P En tout cas ça mesure très bien, et cela donne encore plus de motivation pour s'entraîner dur... Vu que l'on peut mesurer précisément notre force à chaque séance. Sachez que le 180 kg faut vraiment s'appeler Hulk pour l'atteindre... j'ai moi même de la puissance dans les mains, à broyer les mains de mes ami(e)s sur demande ahahaha... Et lorsque j'ai vu mon score sur la machine j'ai fait la gueule ! En résumé un appareil qui offre une grande marge de progression dans le temps vis à vis de la mesure. Ensuite il faudra acheter des appareils de GRIP plus adaptés pour atteindre les 180 kilos un jour... peut être! (Nan en réalité laissez tomber... Même Ronnie Coleman était TRES LOIN des 180 quand il l'a testé)
