Quick answer
Only if your kamado is 61 cm (XL or Big Joe). The listing gives 45 × 35 cm, 4 kg and 900 °C; the diagonal is about 57 cm (by calculation), so it will not fit a 46 cm Large or Classic. It scores 4.6 out of 5 across 132 reviews, but it states no kamado fit, and delivery to Spain is paid and slow.
Rectangular cordierite, 45 × 35 cm and 4 kg, from a German barbecue brand. Its diagonal is about 57 cm (by calculation): it will not go into a 46 cm kamado, but it will into a 61 cm one.
The Moesta-BBQ 19217 is a rectangular cordierite pizza stone, 45 × 35 cm and 4 kg according to the listing. The brand appears as MOESTA BBQ EST. 2012 and the manufacturer is MOESTA-BBQ, which says it makes its products in Ostwestfalia, Germany; the listing does not say where this stone is made. It states a heat resistance of up to 900 °C (the details table gives 1652 °F, which is the same), it is grey-brown and it is hand wash only. Amazon ranks it 29th in its list of pizza stones for barbecues and smokers, with 4.6 out of 5 across 132 reviews.
What sets it apart from the other stones in the catalogue is its size. Against the 38 × 30 cm ones already published, 45 × 35 cm is 1575 cm² of surface against 1140 cm², about 38 % more. That leaves room for a round 30 cm pizza without touching the edges, or for a rectangular focaccia. The listing mentions bread, focaccia, tarte flambée and frozen dough, and credits the cordierite with drawing moisture from the dough and spreading the heat.
The big constraint on a kamado is the diagonal. At 45 × 35 cm the diagonal is about 57 cm (by calculation; the listing does not publish it). On a Large, a Classic or any kamado with a 46 cm grate it will not fit in any orientation. On an XL or a Big Joe, with a grate of roughly 61 cm, it fits with about 4 cm to spare across the diagonal, again by calculation. So this is a stone for 61 cm only; if your kamado is another size, the sizing guide helps place it, and on 46 cm the safe choice is a round one such as the Rösle VARIO 30 cm or a small square one such as the Lithos Materie 30 × 30 cm, whose diagonal of about 42 cm fits in 46. Mind you, the 38 × 30 cm rectangular stones also have a diagonal of about 48 cm, so measure your grate first. As with any stone, the set-up wants a deflector underneath so the heat arrives indirectly; the method is laid out in the Neapolitan pizza recipe.
The drawbacks are on the listing itself. One bullet gives a height of 12 mm while the dimensions table says "0,1 Grosor", two figures that cannot be reconciled. The title has a typo ("cordiita"). The texts mention gas grills, kettles and brands such as Rösle, Weber and Napoleon, but cite no kamado, so the fit is worked out from measurements. The Smokin' PizzaRing the brand recommends for top heat is for barbecues; a kamado already radiates heat from the dome. It is 4 kg of stone: the prudent course is to put it in cold, let it cool inside and, if it has to be handled hot, wear heat-resistant gloves; at high temperature, open the lid slowly to avoid a flare-up. On top of that, the offer for Spain has paid delivery and a long lead time.
In one sentence: a big, well-rated stone that only makes sense if your kamado is 61 cm and you want surface for focaccia or generous pizzas; otherwise a smaller stone, measured against your grate, does the job.
A well-rated 45 × 35 cm stone, but only for an XL or Big Joe: the diagonal of about 57 cm will not fit in 46 cm. If that is not you, look for a smaller one and measure first.

Cons
- Diagonal of about 57 cm: will not fit a 46 cm kamado, XL or Big Joe only

- Paid delivery and a long lead time on the offer for Spain
Who it's for
For anyone with an XL or Big Joe who wants more surface than a 38 × 30 cm stone: focaccia, flatbread or large-format pizzas.
Not for
If your kamado is a Large, a Classic or smaller: the diagonal (about 57 cm) will not fit in 46 cm. Nor if you need it in a hurry.

AMZBBQ Pizzaschieber: perforated aluminium pizza peel, 40 cm
The 40 cm perforated aluminium peel fits the 45 cm side of the stone with about 2.5 cm to spare each side, so you can load the pizza without brushing the edges. It is another piece for 61 cm kamados only, like the stone, and you buy it separately because the stone does not include a peel.

WMF BBQ Heat-Resistant Leather Gloves 40 cm (Pair)
That is 4 kg of cordierite on a grate that burns; if the stone or the grate has to be moved while hot, a pair of long heat-resistant gloves is worth having. At 40 cm long, the WMF leather ones cover the wrist and part of the forearm, the area that gets close to the mouth of a 61 cm kamado.

Rösle Pizza Wheel Cutter
A 30 cm pizza or a rectangular focaccia cuts better with a wheel than with a knife. It is a small purchase that gets used on every bake and does not depend on the size of your kamado.

FAQ
Will this stone fit my kamado?
Only a 61 cm one, such as the Big Green Egg XL or the Kamado Joe Big Joe. Its diagonal is about 57 cm (by calculation; the listing does not publish it). On a Large, a Classic or any 46 cm grate it will not fit, and on a MiniMax or a Joe Jr even less so. If yours is 46 cm, the safe bet is a round stone of about 30 cm or the Lithos Materie 30 × 30 cm, with a diagonal of about 42 cm; the 38 × 30 cm rectangles have a diagonal of about 48 cm, so measure your grate before ordering.
How does it differ from the 38 × 30 cm stone in the catalogue?
Size and little else. This one has about 38 % more surface (1575 against 1140 cm²), handy for focaccia or flatbread, but it demands a 61 cm kamado. The Blumtal 38 × 30 cm is more compact and comes with a peel, although with a diagonal of about 48 cm a 46 cm grate is still worth measuring first. Both are cordierite; this listing includes no peel or extras.
The listing mentions Weber and Napoleon. Is it any good for a kamado?
The listing cites gas grills, kettles and brands such as Rösle, Weber and Napoleon, but mentions no kamado. So the fit is worked out from measurements: a flat cordierite stone does not depend on a brand, only on fitting the grate and having a deflector underneath. On a 61 cm kamado, 45 × 35 cm goes in with about 4 cm to spare across the diagonal (an estimate). With no declared compatibility, check your diameter before buying.
How do you clean it, and what temperature does it take?
The care the listing gives is hand wash. The stated resistance is up to 900 °C in the bullet and 1652 °F in the table, equivalent values. As with any cordierite stone, the sensible course is to heat it along with the kamado and avoid sudden temperature swings, although the listing gives no usage instructions. It is a 4 kg stone: let it cool inside the kamado and do not wet it while it is hot.
