Core Surge® Adjustable Smart Grip Strength Trainer with Digital Counter – 5–60kg

Been using the GripX trainer for 2 months, mostly during work breaks and warmups before climbing or on the way to the crag. Didn’t expect much (just another squeezer), but it made a real difference—I’ve gone up a grade on the MoonBoard. The rep counter helps me stay consistent, and the different grip options keep it versatile. Solid, durable build too, no need to baby it, just toss it in the pack with the rest of the gear.

I broke my arm and got gripx to stay active during recovery. Now my friends can’t stop playing with it . Looks like I’ll need to get another one. (or two 😄)

Small but powerful! This tool is great for injury prevention and grip strength. The analog counter is a nice feature, and I love that I don’t need batteries.

I use this every day while watching Netflix. My grip is noticeably better, and my climbing endurance has improved. It’s a must-have for any climber.

This has really helped with my grip endurance. I use it while studying, and my fingers don’t fatigue as fast when I climb. Amazing product!

Didn’t expect much, but this has become my go-to warm-up tool!

I like the variety of grips I can train with this. The adjustable resistance lets me push myself more over time. Great for injury prevention too! The e-guide is super useful, and tracking progress has made me more consistent with my training.

I love how compact this is! I keep it in my bag and use it while commuting or during breaks at work. The adjustable resistance is a game changer, and I can feel my fingers getting stronger. The tracking sheet is a nice bonus—I actually use it daily!

Great product overall, it delivered in most aspects I was expecting. The spring inside has become squeaky, hence the 4/5 star.

Really like the product. Sturdy construction, clear exercise guide and works. Seeing small gains in 2 weeks. Easy, portable and fun. Great product

Thanks for sending me information on the product as requested. After figuring everything out woth the mechanics of this grip trainer I love its versatility!

Took a while for it to show up, some knockoff shipping courier company from overseas. Once it showed up though, it has been great. The Counter is a nice touch and the finger tip applications are sweet.

Took a while to show uo but overall im impressed with the packaging and how well made it is.

Outstanding product! I love how versatile it is for building different types of grip strength plus the squeeze counter makes it easy to keep an even pump while focusing on other things.

felt stronger after 1 week. Felt stronger on crimp holds. Family love them too

I'm more confident on fingery little moves in just a couple of weeks. Great product. It's letting me work on a weakness every day instead of once a week. Thanks team

overall seems like an enhanced grip trainer. The finger strength trainer, however, doesn't help much since the resistance doesn't vary at all (thus relegating it to just warming up the fingers, rather than actual training). For me, I was looking to get a grip trainer to supplement hangboarding anyway so it works, but if anyone was looking to improve individual finger strength, I think they'd be disappointed.

Great tool and have noticed benefits of training with it already. Quality product, only criticism is I would like to have the option to adjust the resistance to the finger crimps.

The pinch and grip function is great, but I wish there was a way to adjust the tension on the finger/crimp buttons.

Versatile and adjustable. Helps train my hands and relieve soreness after climbing.

Honestly didn’t expect much, but Grip X is surprisingly effective. I’ve been using it almost daily — short sessions, nothing crazy.I can already feel more control on small holds. Love how I can train at home or even while watching a movie. Definitely recommend it if you want to stay consistent without overcomplicating things.

I would appreciate it if you sent me training instructions in English.

I noticed a difference in my grip after just a few weeks! Great for warming up before a climbing session. My fingers feel stronger, and I can hold onto slopers better now.
