Hi. I wanted to know if the bellows change according to the value or if they are all of the same material and duration since here in Argentina one leaves me $ 1790 https://articulo.mercadolibre.com.ar/MLA-686147028-fuelle-lavarropas-lg-carga -frontal-f1422-f1400-f1380-_JM and the other $ 3400 that claims to be national https://articulo.mercadolibre.com.ar/MLA-719379237-fuelle-de-lavarropas-lg-f1370-1380-1389-1400-1422-nacional-_JM and another also $ 3400 and is imported https://articulo.mercadolibre.com.ar/MLA-719385918-fuelle-de-lavarropas-lg-f1370-1380-1389-1400-1422-importado-_JM I would appreciate the information, if they had bad experience with a cheaper one or if it is just that they charge what they want and it is more of the same. Thank you!
