The HUUM CORE in black is gorgeous. The matte finish and clean Scandinavian design look stunning in my sauna. It holds a generous amount of rocks which gives soft, even heat and amazing steam. Heat-up is quick. Pairs with the HUUM controls for app control. A premium heater worth the price.
The large rock capacity on the CORE produces the softest, most enveloping steam I've experienced. Heat-up is fast and the heat is gentle and even. The black design is beautiful and modern. Solid build. The app control via the HUUM controller is a great addition. Love it.
The HUUM CORE Black elevated my whole sauna. The design is sleek and the heat output is excellent. The big rock bed means soft loyly and even warmth. Heats quickly. Had an electrician wire it. Worth every penny for the quality and aesthetics.
No complaints about performance, the CORE heats fast and the steam is soft and beautiful. The black finish is gorgeous. It is a premium price, but you get premium build and design. The large rock capacity is the highlight. Recommend pairing with the HUUM app control.
After years with cheaper heaters, the HUUM CORE is a revelation. Even heat, soft steam, quick heat-up, and a stunning black design. The build feels bombproof. App control makes preheating effortless. Highly recommend for a serious sauna.
