Real-world data for the Siguro AC-C140W Cool 9 - Test to cool a 25m² room without direct sunlight, with the windows sealed and only the fridge running in the flat – I left for 4 hours and left the air conditioner running in ‘Cool’ mode at 16°C – Result: a drop in temperature from 29.5°C to 27.6°C. If a computer or a large electrical appliance is running at full capacity, the ‘air conditioning’ won’t lower the temperature by even 1 degree. In theory, a portable air conditioner that draws in air from outside via a second pipe – and does not create a negative pressure – would work, or an air conditioner that vents cooled air into the flat and can be placed on the balcony, such as the Sinclair AMC-11P
It could be returned within 14 days
It might just about cool a toilet measuring 3 square metres
An overpriced cold fan
Physically, it simply cannot work because it only has one pipe outlet – the warm-air outlet – and all the air that the air-conditioning unit blows out of the flat must find its way back into the flat through the gaps from outside (logically, otherwise it would create a vacuum in the flat)

I bought it about a year ago and I wouldn’t buy it again. It’s noisy, and in the end it doesn’t really cool a small room down much. As soon as you switch off the air conditioning, the temperature in the block of flats rises by two degrees again after a short while (a couple of minutes), and as you can’t sleep with the air conditioning on because it’s so noisy, you end up in a sauna again in the morning. The exhaust duct heats up and then catches fire. In my case, the window seals come away when they get hot (yes, after a year, but I wasn’t expecting that…). Next time, I’d probably go for something other than a portable air conditioner, or perhaps a more powerful model.
It keeps you cool, so it’s better than nothing in this heat
Option to control via the app
Option to schedule the device to switch on remotely via the app
Remote control included
It’s quite loud even at lower revs
It’s practically impossible to sleep with the air conditioning on
The exhaust hose is made of plastic, so it heats up and conducts heat

If it cooled as well as it makes a racket, that would be brilliant. And vice versa. It’s our punishment for not installing a fixed air-conditioning system when we renovated the flat.
Easy to assemble and commission
It’s not for sleeping
Sleep mode is a joke; it’s just a lower fan speed. As someone mentioned here, this setting is very noisy; then there’s the second, higher setting, and that’s even worse
It’s not for sleeping

We’d need something a bit more powerful for our loft flat, but it’s a great buy in the sale. It can easily cool a medium-sized room (20 m²). After reading the reviews, I was worried it would be too noisy, but it’s not that bad. It’s not really suitable for sleeping, but you can work or watch TV whilst using it.

The air conditioning cools very effectively. The change in air quality is noticeable within the first 10 minutes of operation, and in about an hour it can reduce the room temperature by around 2 °C, depending, of course, on the size of the room and the surrounding conditions. Even at maximum power, the noise level isn’t as high as some reviews suggest, so you can carry on with your usual work or watch TV without any problems. In the price range of around 6,000 Kč, air conditioning offers very good value for money, particularly for use in an attic flat during the summer months. However, it is important to bear in mind the typical trade-offs associated with portable air conditioners, such as a shorter drain hose, the need to drain condensate regularly, and higher noise levels during operation. All in all, it’s a great air-conditioning unit with very good cooling performance at a reasonable price.
It quickly cools a room of around 18m² plus the hallway
2 speed levels
Moisture wicking
Compact and space-saving dimensions
The pack includes a free fabric cover with a zip to protect the window
The drain hose isn’t very well designed. It tends to fall out of the plastic end caps, so I recommend securing the joints firmly (for example, by gluing them). At the same time, the hose is quite short, although this is a common shortcoming of most portable air conditioners
The condensate drain should be checked regularly. When the air humidity is high, the air conditioning system can produce approximately 1.5 litres of water in 1.5 hours of operation
In my experience, the Sleep function does not offer any significant benefits. Even in this mode, the sleeping aid is still too noisy

It cools what it’s supposed to
Control via mobile phone using Wi-Fi
High noise levels, particularly in the so-called night mode, which is supposed to be quieter, but there’s no difference compared to the main mode (perhaps it’s a fault with this particular unit?) )

Úprimne neviem, ako si predstavujú, že by tá klíma mala pracovať. Mám ešte nižšie okná, a hadica na odvod teplého vzduchu mi len tak tak dočiahne mimo, cez poslednú hranu okna pri pántoch sa tlačí teplý vzduch naspäť. Aby tá hadica na kondenz bola použiteľná, musel by som jej buď prevŕtať cestu cez omietku von, čo nemôžem... Alebo by som musel mať klímu nad kuchynským dresom, ale jedine kam by som potom mohol tlačiť teplý vzduch by bolo hore digestorom. V noci je tu teplo, ale ten kompresor tak strašne hučí, že to zobudí aj susedov. Klíma robí všetko čo má, za tú cenu, ak ste v prenájme a vidíte tieto trópy, tak radšej alzácka Siguro, jak riskovať Aliexpress. Len škoda, že musím mať na noc ešte navyše tichý ventilátor, lebo aj tá funkcia, kedy nebeží kompresor a len to točí vetrák je príliš hlučná.

Great air conditioning for the money.
It cools a 20m² room and the hallway
The noise level is standard; if you want complete silence, you’ll need to get an outdoor unit – for a completely different price, of course.
