## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect for this Current Heatwave
*by J***N on 30 June 2025*

I purchased this Air Cooler back in the depths of Winter last November at a real bargain price of under £20!! and have had it in storage since then. It has proven a real boon during this current heatwave, providing a three speed cooling breeze with horizontal and vertical wind direction.As I type this review, I am sitting in my lounge with the breeze directed towards me. Note that, unlike the usual air conditioners, this unit doesn't require an exhaust hose, nor does it dry out one's eyes, because of the evaporative cooling system in place.I can thoroughly recommend this unit, but do try and purchase it during the Winter months as I did.

### ⭐ NOT an air cooler
*by P***K on 6 September 2023*

It’s a fan, a nice one but for the price there’s better fans, I bough this because it is an air cooler. It doesn’t cool the air in a small/medium sized bedroom. Literally didn’t take the temperature down even 0.1 degree after running for 2.5hrs and changing the ice packs twice

### ⭐⭐⭐⭐⭐ Perfect for a small room
*by M***D on 12 September 2023*

Hi, I’m a university student and we got a heatwave in the UK and my room was so hot and humid. It actually felt like an oven but today I received the small AC it was perfect. I fill it up with water put ice on top or use the ice packets and just point it straight at me. Of course, the room doesn’t get cold that much but if you want to use it to cool yourself down, it’s perfect I just pointed at me go to sleep do my work etc. I would recommend it if you are a student that is living in a dorm or in a small suite.
