User reviews

Temperature Deviation Alarm

Will future updates include an alarm notification should the temperature within the cooler rise say, 10 degrees?

Excellent fridge.

I love my Truma and the excellent customer service. Thank you Truma.

Error code makes the cooler almost useless

The don’t kill my battery setting is beyond irritating, won’t let you see what your actual temp is and should let you kill your battery if you want to. Let me decide how I want to use my so called smart cooler please, what a waste of money-

Previous version was WAY better

I do not understand why app developers feel the need to fix things that weren't broken. The previous app was way better and worked flawlessly. Example; the previous version showed the 2 zones with a picture. You always knew which zone was which because they are different shapes and volumes. Now the app just gives you zone 1 and zone 2 with no way of knowing which is which. You can't just go by left or right because this thing has the controls on the end and the lid is reverseable. Also, previously you could see and control both zones from the same screen. Now you have to toggle between at least 2 screens just to control and monitor the temperatures.

Can I please have the old version back?

Great state of the art app

Just purchased the C30 and downloaded app. The qr code they included with packaging is a great idea. The app is fully functional and allows me to name my cooler and control it fully.

Glad I purchased this cooler and highly recommend it.
