劣質洗衣機入水喉

上面白色是最易找到,$2x. 但漏水. 灰色, $4x, 是假冒 "MADE IN ITALY"  假冒 "MADE IN ITALY"  的標緻  左面是白色膠喉的喉頭, 右面是灰色膠喉的喉頭, 上圖左面是真正 好貨 ( MADE IN ITALY )灰色膠蓋.右面是冒牌 白色膠蓋. 膠蓋在安裝扭緊時爆開  上圖左面是真正 好貨 , 標了其他規格.右面是冒牌, 單單印了 MADE IN ITALY  好貨的膠蓋是可以下移, 露出喉頭及黑色軟膠墊 黑色軟膠墊是有坑紋. 質感較柔軟. 緊後可以"迫實"水龍頭 及喉蓋, 沒有滲漏 正板 MADE IN ITALY 賣 $4x, 價錢絕對合理. 冒牌貨在旺角新填地街買的, 也是$4x. 真是要小心!!! NB: MADE IN ITALY 是否真正 意大利制造實在無從考 証
