Works fine

Khione guys asked me to place a review. Delivery took long but very satisfied with my investment. I estimate that in approximately 8 months I have earned my money back in terms of buying bags of ice. Cold cheer!

Works fine

So far so good. Delivery was on time and without issues. I’m using a 1200 liter pool and the machine is more than strong enough to get the water really, really cold.

Red lobster style

Well, all I can say is that I look like a red lobster when coming out of the water after 10 minutes submerged. Awesome product guys.

Strong cooler

I never expected the cooler to be so strong (I have the C3). In just 3 hours I have subzero temperatures. Awesome.

Works good

Started cold therapy 2 years ago. A cold shower doesn’t top a real ice bath, but those bags of ice.. a hassle. I have a CoolCube C3 and dude, after just a few hours of cooling it's freezing, like 1 degree. Perfect!

People should know that these machines can make your bath way colder than bags of ice ever can. What a difference.

Hell yeah daily ice baths. I use a 1500 liter pool and my CoolCube is more than powerful enough. Great stuff.

Lyme

I have Lyme disease. Cold baths help me but getting bags of ice is not efficient. A CoolCube is. Great work guys.

Usage is acceptable!

The C3 consumes about the same a fridge/freezer combi. But only when it’s on. It takes me less than 2 hours to get to 3 degrees.

Satisfied.

Be careful; the cooler (either the C2 or C3) is heavy! Prepare the position where you want to place your CoolCube. I didn’t prepare that well. Apart from that; very capable machine.

Works fine

Goede klanten service, nemen uitgebreid de tijd voor je. Ik gebruik de CoolCube™ C2 nu ruim een jaar. In zo’n 3-4 uur krijg ik mijn bad op 2 graden. Koud!

Works fine

The guys from Khione asked me to write a review; I’m content with the cooling machine I bought from them. I live in the Mediterranean and can now easily practice with outside temperatures of 30+ degrees. Haven’t been sick since I started practicing cold therapy.
