I got this heater for one of the bedrooms that is always very cold and can not be warmed by the central heating without cooking the whole house.
The unit feels very well constructed and the wheels and cable reel are very handy to have.
It will heat up a small to medium room up in no time at all and I am finding my self having to turn it down a notch as it warms the room very effectively and quickly, even on the lower power usage setting!
Although it doesn't say in the description there is a small neon indicator light that shows when the heater is on and heating, which is rather useful.
I only gave it 4 stars as the power cable is a little on the short side at just under 1.40m long, although I could probably fit a longer one if need be. The heater is only going to draw 7 amps max on the highest power setting (1500watt/230V=6.52amp) so as long as you use a thick cored wire rated at 13amps it should be fine.
Summery: A decent oil filled heater that is very fast and effective at heating small to medium rooms.
Update: During the freezing winter of 2010 my boiler broke down and this heater was able to heat my bedroom all night long.
