On the portability front, it scores well with easy-to-move casters and side handles, making it simple to relocate as needed. The included 'Follow Me' remote control allows for precise temperature management, adding a layer of convenience. The product also comes with a complete installation kit, which simplifies setup.

However, it weighs about 56.8 pounds, which might be a bit hefty for some users. Additionally, despite its features, the air conditioner has a fixed capacity of 0.8 liters for dehumidification, which may require frequent emptying in very humid conditions.
