First, there should be a 800 Watt marble heating (was among others at a discount store for the same price in the offer, so even the thought of a purchase) are, but browsing on Amazon I almost stumbled on the Magma-heating (because I wanted to see, How much does something like this). After some consideration and a little persuasion ("She has only half the power! Can no good!" "But that costs twice so must / be better more efficient!", Etc.) was to be a matter of purchases. If necessary you can also return yes.
How can you say it: The installation had happened quite easily and on a Saturday night. Ever since the first power-up (and back off) and the rest of the family is convinced: The heating may absorb less power than other offers, but the stone slab keeps the heat even really off long after. We also have a classic electric heating in other rooms with marble slabs. The cool but much faster. Compared explained as well as the similar heating power at half the (electrical) power.
That's me then like worth paying extra, especially considering, as the benefit remains the same yes (and you also still effectively saving half in utility bills!).
To send one should say that the plate was really packed robust and exemplary. At the same time advises one of the manufacturers but also, prior to the adoption to check the product for transport damage (which we had overlooked, but there were no problems). After all, anyway times happen and those things are actually already more sensitive than pure metal devices, for example.
