I have the Lakelands airer, the smaller size one with two tiers and it's double the cost of the one you linked. Mine has about 2 metres more drying space but not all the bars heat up on mine, whereas I think it says your example does. Only my internal bars not the outer framework heats up. Reading the description of yours it says all bars heat up.
I really pile mine up. I cover all bars and then hang items on hangers all around the sides and cover it with a sheet. Would your one be able to cope with this extra weight if you need to do that. Would it topple.
The only niggle I have with mine that yours would not have, is items drying on the lower bars can touch the floor ie trousers so I have to faff about placing things carefully. If I hang the trousers on the top bars I need to think about what is going underneath incase it's too bulky and will take longer to dry as the trouser legs dangle down alongside the item on the lower bars. Looks like that won't be a problem with your example.
Personally if you have the space for a longer rather than taller model and at half the price then it seems a bargain. Is the guarantee as good as Lakelands too as theirs is good.
If it were me I and I had space, then I would buy it. The running costs are similar, the drying space is almost the same, the style is fine if you have space and it's half the price of Lakelands one. I think Aldi was selling a similar one to your example last year for around the same sort of price but not sure about the size or running costs etc.
