It looks like they are stepping up. They responded to my email first thing this morning with this –
Scott,
Thank you for your email and your feedback. When these lures are placed back into a sealed tackle tray after use and exposed to direct sunlight/heat for a length of time, the combination of moisture, heat and a closed box will create a significant amount of pressure. Another cause of this is leaving the lure on the dashboard of your vehicle. Extreme heat causes air to expand inside and seams to split. As these lures are made of a plastic material, the below issue will happen. We suggest storing such items away from direct heat and sunlight so that this will not occur. This is not considered a manufacturer’s defect.
With that said, please send them in to our warranty department. We will replace for you.
Happy fishing!
