It's been a couple years since I bought some, probably not due to get more until spring. Mine were similar to the first photo, but I add some hardwood pellets to them, about a half cup of hardwood pellets to 2½ cups of corn cob pellets, shake them up and heat in the microwave for 2 minutes, then put in the tray and light. They work just fine for me! Love the aroma of the corn cob smoke, grew up with it!
