I bought this mini oil-filled radiator to use in my mini-camper van to use for winter camping where it's perfect. It warms up my van very quickly and, unlike fan heaters, doesn't make the air dry and stuffy. It's silent in use so is suitable to use overnight.
Design is good: it's very neat and tidy with a quality build. It has a small footprint, is highly portable with recessed grips and has a 6-position thermostat and when drawing power (which doesn't seem to be too often) the red power button illuminates. There's also a frost-guard setting making the heater suitable for use in a loft, porch, caravan, boat or anywhere there's a risk of pipes freezing or simply to help prevent damp.
In use it produces a steady, lasting radiant heat and, unlike using a fan heater, the room doesn't go cold immediately it's switched off. Also, it after being switched off it still radiates some heat at it gradually cools down - ie 'free' heat! I've tried other 500w mini oil radiators, including a Dimplex 500w model of very similar specification and some from budget stores but this is by far the best and seems to radiate heat much more effectively.
Shortly after buying it, our gas central heating boiler broke during a spell of cold, damp foggy weather followed by snow so it was brought into the house for indoor use. Although it's only 500W and not designed for heating large rooms it warmed up my small 8' square office very effectively and made a noticeable difference in our 16 lounge.
It's economic in use and perfect for a small room such as a bedroom, bathroom or for use in a boat or campervan where space is tight.
A highly recommended purchase from a reputable manufacturer and backed by a 5 year warranty - excellent. Although there may be some cheaper radiators available, many of which I've tried, you get what you pay for and this is by far the best in my opinion.
