Safety is a priority with this heater, as it includes overheat protection, a tip-over switch, and automatic thermal shutoff, making it a safe choice for homes with children or for use in bathrooms. Its slim design and portability, aided by four wheels and a carry handle, make it easy to move and store. Additionally, it helps save on energy bills by allowing targeted heating rather than heating the entire home.

However, it weighs 8.3 kg, which might be cumbersome for some users to move frequently. Noise levels are low, ensuring a quiet operation, which is beneficial for bedrooms and offices. The energy efficiency is good, but oil-filled radiators generally take longer to heat up compared to fan heaters. The heater's white color and pedestal form factor blend easily into most home decors.

The built-in safety features, including tip-over protection and overheat protection, add peace of mind, especially in homes with pets or children.

Its compact size and built-in handle make it easy to move, while the heavy-duty castors help you roll it around without lifting, although it's important not to move it when it's on to avoid damage. On the downside, the heater is relatively heavy at 8 kg, which might be a consideration if frequent relocation is needed. It doesn’t specify any advanced energy-saving modes beyond the adjustable thermostat and heat settings, so energy efficiency depends largely on usage habits.

The heater's portability is another plus, thanks to its pre-assembled easy wheels and carry handle, allowing for hassle-free movement across different rooms. Its elegant white design would fit nicely in most home decors, adding an aesthetic appeal beyond functionality. A 10-year manufacturer's warranty underscores its durability, securing long-term use.

Potential buyers should consider its size and weight—at 17.52 kg and dimensions of 51.9 x 16 x 64.99 cm, it may not be the best fit for smaller spaces or for those who require frequent repositioning of the heater. While the medium (1,400 Watt) and minimum (1,100 Watt) settings provide options for energy efficiency, it might still consume more electricity at maximum power compared to some alternative models. Noise levels are generally minimal with oil-filled heaters, offering a quieter heating solution compared to fan-based units. This radiator is well-suited for providing lasting warmth in larger rooms or spaces where its size can be accommodated without issue.
