Product Strengths Across Both Models

• Many reviewers emphasise how quickly the heater warms up the caravan/camper.
• Even in very cold conditions, users reported a steady, comfortable heat output.
• Several mention that the unit “paid for itself” on the first cold night, underscoring how valuable it is for extending the camping season.

Fuel efficiency & low power draw

• Customers appreciate that the heater uses minimal diesel and battery power, making it suitable for off-grid camping.
• For longer trips, this translates into cost savings and fewer refuelling stops.

DIY-friendly installation

• Seen as a step up from cheap imports (e.g., one replaced a CDH and noted obvious upgrade). Heater runs straight away without fiddly pump angles or issues.

Excellent comfort & usability upgrades (Bluetooth model)

• The Bluetooth control is a major selling point — praised for allowing users to start the heater from bed or outside the van.
• This feature is especially valued by campers who don’t want to step out into the cold first thing in the morning.

Weaknesses / Cautions

• While details are limited, occasional dissatisfaction likely tied to specific installation issues, expectations not met, or rare product faults have been identified within customer reviews.

Bluetooth adds complexity

• Although generally praised, having Bluetooth functionality could introduce extra setup or troubleshooting steps (though not specifically flagged as a widespread problem in reviews, it’s a common theme with tech features).
• For users less comfortable with apps or connectivity, the standard version may be a simpler fit.

Limited detail on functions 

• Some users felt the instructions didn’t explain the different heater functions in enough depth.

Controller design

• One person noted the controller cable exits from the bottom, making it tricky to get a clean, seamless look.

Learning curve for features

• While most found it easy to install, some still needed to call for extra guidance.
