EcubMaker 12V 40W Ceramic Cartridge Heater for 3D Printer Prusa Mendel

WARNING: These are NOT 6.3 mm diameter and are NOT 25.4 mm in length. The products delivered are 6 mm diameter and 21.5 mm in length.I'm still giving them 2 stars because these look like quality parts, but they just aren't what the seller stated! Not even close!If you are looking for replacements for the original FlashForge Creator Pro heater cores, these may fit within the aluminum block, but they are VERY loose. Pretty disappointed that the seller either can't ship the right parts or is directly lying about their product to try to differentiate themselves in search results.At least the thermocouples sold by EcubMaker are identical to the Flashforge Creator. Was hoping they would be a good source for heater cores as well - GUESS NOT!Seller states the following in their description:Brand name: EcubMaker
