Customers say
Customers find the diesel heater to be a great unit that puts out lots of heat and has low fuel consumption. However, the functionality and ease of use receive mixed feedback – while some say it works well and is easy to use, others report it won’t work upon arrival and have issues with the user interface and instructions. The noise level is generally quiet, though one customer mentions it makes a beeping sound. Additionally, the battery life is problematic as the remote has no battery, and the instruction quality is poor.
