Title: Used to be a great tumbler
Product review: I used to love these tumblers. In the past 7 years I have owned 3 of them. I still have the original (lost the other two) and the seal finally went on it so I decided to stock up on some more.To my surprise the quality had went down the drain. I ordered two of them and both of them leaked. Since I am a engineer and can't leave "doesn't work" alone I disassembled the lids to find that the issue was poor injection molding which lead to sink marks in the seals contact surface.Maybe the mold for this lid has met its demise and that's why these cups are no longer available, maybe I got unlucky, or maybe Trudeau's quality standards have went out the window? All I know is I would not buy another one of their "Leak Proof" products without seeing, in person, that it is actually "Leak Proof".
Would you say this review depicts the product in a flattering or unflattering light?
