i was satisifed with it when i first got into cubing, it was pretty good and fun to connect and use on my phone and actually be able to track stuff super easily, i did get a looooot of lockups though and it feels clacky now but its pretty good

A Lightweight Smart Cube That’s Surprisingly Powerful
The GAN i Carry 4 is incredibly fun to use, offering Bluetooth tracking and smooth magnetic turning in a lightweight design that feels great for long sessions. The UV coating adds grip, and the cube performs like a premium non‑smart flagship. SpeedCubeShop delivered it quickly, and it’s perfect for anyone wanting to improve with smart analytics.

A Lightweight Smart Trainer
The i Carry 4 delivers a streamlined smart‑cube experience without the bulk of earlier GAN smart models. It connects easily to the CubeStation app and provides reliable tracking and analytics. While it doesn’t reach the depth of the i3 or i5 series, it’s an excellent training companion for data‑driven practice.

Where's the Center Cap Opening Tool?
I'd give it a 5 star, but mine didn't come with a 'Center Cap Opening Tool,' so I can't make any adjustments to the tension without feeling like I'm going to break the cube because the center caps seem to be locked in place on 4 sides , so having a thin finger nail isn't good enough to open it safely and effectively :( The manual shows a picture of the Center Cap Opening Tool in action, as well as what the Adjusting Tool for tension adjustment looks like, but my purchase DID NOT come with the Center Cap Opening tool and I'm so sad and discouraged...
...Other than that, the cube turns smoothly and rather quietly right out of the box and the magnets have a decent strength. The app works just fine for the blue tooth feature and I love how it records my stats and the training it offers, as well as a "shop" to spend in-game-points on...I just REALLY wish my order came with that Center Cap Opening Tool so I could adjust my cube... :(
