Looks and feels wonderful, but the fitting and bulb feel a bit cheap for such a famous product. I think it used to be incandescent; it feels as though the fitting was changed recently for one of far cheaper build quality.
Luckily, the fitting is easily replaced because it's completely separate from the rest of the product. We haven't changed ours yet, but in the interim we've used a Phillips Hue e14 Lustre bulb in ours (the one that comes with it is cold and rattles around, not good). The new bulb is a warmer light and really improves the feel of the block lamp (as well as being dimmable).
So, you won't regret buying this, but I would say it's let down by the cheap fitting.
