I didn't think it needed explaining - by your comment it would make sense to purchase a cheaper model heater as it offers the same functionality at a cheaper price. As everyone else seems to be voting for an identical wattage heater for more money, the emperor's new clothes analogy works (used in reference to a situation in which people believe or pretend to believe in the worth or importance of something that is worthless (in this case a brand name), or fear to point out an obvious truth that is counter to prevailing opinion.). I keep forgetting this is HotUKdeals...
It's ... a heater. That makes things warm. And it's very cheap at the moment. You'll need to explain your metaphor a bit better if you want people to understand what it is you're trying to say.
Wow - do you guys really like the emperor's new clothes or what?
Please do not say summer is over... (skeptical)
I've had lot of stuff from CPC in the past. Some good some horrendously bad. For something like this which isn't fixed in one place and likely to get some abuse I would say it's worth spending few quid extra for branded stuff for the sake of build quality and design. Possibly longitivity too.
