Product review (2 stars): I would give the company's customer service 4 stars for "crafting" a part that fit and works just fine.
The item I received was not as pictured, did not match the item #WB06X10633 and did not fit. The arms of the assembly were the right width, but the center stem was to long, causing the whole thing to sit too high in my microwave and wobble as it turned.  I texted the company about the problem and included photos, and asked if they had the correct part available. They responded within a day or two and asked if I wanted them to send a correct part or if I wanted my money refunded. After I told them I wanted the correct part, they sent me the same part, but the center post had been cut down to the correct height and fit perfectly.  I returned the first item to them.  It was disappointing to not get the correct part in the first place, and although the second part I received was not really the OEM part that is pictured, I would give the company's customer service 4 stars for "crafting" a part that fit and works just fine.
