Believe In Your Choose

S8 Pro MAX-Thin as cicada's wings — remarkably thin and lightweight. Setup was straightforward, and I had it running within a few minutes. The screens are bright, the unit feels well-built, and it folds away neatly. If you spend a lot of time working away from a permanent desk and miss having multiple monitors, it's definitely worth considering. 

Josh Hayes

Many say the K3 isn't portable. But they're missing the point. It's not about carrying it everywhere — it's about bringing the desktop experience anywhere you work. It's an 'unlock tool' that frees your workspace from the desk. Location freedom is the real key to productivity.

Chang Chia-Hao

The S6 don't have to be attached to a laptop but can be set up independently. This allows for multiple configurations and the screens can be rotated, which isgreat when you need to read documents (docx and pdf).We run an online educational institution and need to be able to work even when we're travelling with our caravan.

S6 User, Switzerland

I've been using Kwumsy screens for years, and the S8 Max continues to impress. I travel constantly — working out of hotels, hopping between Zoom meetings, managing multiple projects. The extra screen space keeps me productive and organized anywhere. Lightweight, easy to set up, folds down nicely. For frequent travelers and remote workers — it's a great investment for a mobile office setup.
