Review: Waste of money - Horrible, can barely lower the temp in the room by one or 2 degrees and way louder than advertised. Interface is nice and responsive but that's about it. Not recommended.
Review: Very easy to use. - I'm very happy with this portable air conditioner. Setup was incredibly easy — the window kit doesn't fit my Velux window, I need to buy a separate kit, but it fits my girlfriends windows perfectly and easily.. I can effortlessly move it between rooms depending on where I’m spending time, from my home office to the bedroom. The cooling performance is impressive for the size, and it quickly makes my flat comfortable even during the hottest days. I also appreciate that it’s energy-efficient, helping me save on electricity bills compared to cooling the entire house. The extra features like a dehumidifier and quiet operation make this unit ideal for year-round use.

### ⭐ Waste of money
*by M***M on 26 May 2026*

Horrible, can barely lower the temp in the room by one or 2 degrees and way louder than advertised. Interface is nice and responsive but that's about it. Not recommended.

### ⭐⭐⭐⭐⭐ Very easy to use.
*by S***N on 15 July 2025*

### ⭐⭐ Mediocre at best
*by N***Y on 11 August 2025*

This does emit lovely cool air but that’s where it stops being good. It’s slightly louder than advertised and that was already a bit loud. The “universal” window unit isn’t really, I couldn’t see how it would work to seal a British style window opening rather than a sliding window. But its largest failing seems to be that even if I leave it running for a good while it doesn’t seem to actually change the room temp overall. I mostly use it for a cool breeze on a hot day and it’s honestly quite pricey and bulky for that. Also it is quite heavy so getting it upstairs alone was very difficult and it’s never going to get back down 😂 luckily up here the wheels mean I will be able to put it away come winter.
