We had this microwave with grill and convection function risen as we also daily baking the buns so. At first everything worked fine. Only the loud beeps when setting and shut-down a bit disturbed. The volume in operation is still acceptable. The grill slips easily from the glass plate. After an ample six months the grill function failed. The device was easily the Severin - exchanged service quickly and at no cost. After six months, the unit began to develop in recirculation mode a very unpleasant smell, like schmorender plastic. The unit was again free to Severin - posted service and came back after 14 days. The smell was not turned off. Therefore, we gave back the microwave Amazon. The conversion was handled by Amazon. Conclusion: easy to use as a microwave, do not seem suitable for permanent hot air or grill mode.
