For a quarter of the price, you wouldn't expect it to have all the features of one of the top named brands.
It looks a good option if you want to hold the BBQ temp overnight, but still want to have more involvement in the cook.
I get that a £300 controller can do the whole cook on auto pilot, but that's the same reason I'd never go for a pellet grill. I don't mind accessories that help, but where is the fun in clicking a button and doing nothing. May as well just eat in a restaurant.
If I wasn't desperately tired and covered in charcoal when I eventually started eating 5 hours late, I'm in danger of realising my food doesn't taste that good.
