Solid engineering, runs a bit warm

Impressive that a single connection powers these large displays. The unit gets a bit warm after a few hours of intense design work, but the brightness and contrast are excellent. Very happy overall. Sturdy kickstand included.

Exceeded expectations from Kickstarter - Impressive

Backed this on Kickstarter and it just arrived. I can fit an entire trading desk layout in my briefcase now. These 18.5" displays are crisp, sharp, and bright enough for any room. The integrated stand is heavy duty and holds the weight flawlessly. Setup was very quick on my M-series Mac.

Excellent for professional developers - Verified Upgrade

Highly recommended for coding. Backed it in March and received it recently. The extra vertical space on these large panels is amazing. Driver installation took a couple of minutes but runs perfectly stable. Drains laptop battery fast, so keep a charger close by. The aluminum finish matches space gray perfectly.

Massive 18.5" screens, amazing engineering

So glad I supported this campaign. Blown away by how thin this folds down given the sheer size of the 18.5-inch displays. One cable connectivity works like a charm. Text clarity is exceptional. A masterpiece for productivity! Highly recommend for remote workers.

Incredible Kickstarter Backer Reward!

Just received my backer unit from the Kickstarter campaign! The 18.5-inch panels are absolutely massive and stunning. Color accuracy is phenomenal for my video editing workflow. Premium aluminum chassis feels great next to my MacBook Pro. Incredible upgrade from my old setup! Text scaling is sharp on Windows 11.

Incredible size but portability is tough - Kickstarter Backer

The 18.5-inch screens look great and build is strong, but the entire unit is very heavy and bulky in my bag. It's more of a 'movable desktop' than a truly portable monitor. Also, battery power is depleted in under an hour without wall power. Glad I backed this project.

Great premium monitors, very rigid cable - Highly Recommend

The screen alignment is seamless and looks very high-end. The included USB-C cable is quite thick and stiff, making small desk setups a bit tight, but the performance and brightness are flawless. Text scaling is sharp on Windows 11.

Massive real estate, great for hotel desks - Highly Recommend

Perfect for long business trips where you need a full office setup in your room. It is too massive for a casual coffee shop table, but on a proper desk, it's incredible. Highly functional. Text scaling is sharp on Windows 11.

Perfect for heavy multi-tasking - Verified Upgrade

Fantastic product, but prepare for the weight - Verified Upgrade

Got my Kickstarter reward yesterday. The 18.5" screens are gorgeous and offer endless workspace. The only trade-off is the weight—it's heavy to carry around all day, but that's expected for this size. Build quality is top-tier aluminum. Setup was very quick on my M-series Mac.
