I bought this pen a couple of weeks ago, and I've been using it daily. Why did I get it? Well, as a teacher, I'm always writing and handling things, and I wanted something to keep my hands strong without taking up much space. How does it work? It's simple—just squeeze and use it like a normal pen, but it adds resistance that really works my fingers and wrists. What do I like? It's extremely effective for improving grip and flexibility, and I love that I can toss it in my bag and use it on the go. Is there anything I don't like? Not much, but it took a few days to feel comfortable, and I wish it had a bit more adjustability. Overall, it's a great little tool that does what it promises, and I'd recommend it to others who want an easy way to strengthen their hands.
- Pros: I found this pen extremely helpful for strengthening my hands, which is super convenient since I can use it anywhere without any special setup. It feels very durable and well-made, so I trust it to last a long time with regular use.
- Cons: As it seemed to me, it might not be suitable for everyone, especially if you're looking for a more intense workout, and the grip could feel a bit awkward at first until you get used to it.
