Product Description
Introducing the new and improved RealTruck BAKFlip® MX4 (GEN 3) - an evolution of RealTruck's most popular tonneau cover. This next-generation upgrade builds on everything truck owners already love about MX4, now enhanced with improved functionality, greater durability, and elevated security. The new and improved BAKFlip MX4 is constructed primarily from alloy materials, including heavy-duty aluminum top panels and side rails. Reinforced with high-density polymer cores, each panel delivers a 22 percent increase in overall strength compared to the original model. Security is also enhanced. In addition to BAK's patented auto-latching system, which automatically secures the cover when closed, the BAKFlip MX4 (GEN 3) features re-engineered lock components for improved resistance to forced entry compared to the GEN 2. No matter the cargo you're transporting, you can rest assured knowing your gear's protected. When the weather turns, the BAKFlip MX4 (GEN 3) holds strong. Revised EPDM rubber perimeter seals and tight-fit clamps provide our best seal yet, preventing seepage between the bed cover and bed rails. At the rear of the cover, a 13 percent longer dual-action tailgate seal provides weather protection for the tailgate. This innovative design also improves operation, maintaining factory tailgate functionality regardless of the cover's position. The BAKFlip MX4 isn't only durable, it's also sleek and stylish. Unlike competitors, the BAKFlip MX4 sits flush with your pickup's bed rails, practically disappearing into your truck's profile. And with a sleek, textured matte black finish across all surfaces, the MX4 looks great whether open or closed.

Good flavor, not as full of tubes as I expected.
Size: 4 Ounce (Pack of 2), Set name: G. Orange Cream, Ela Mint
My kids have LOVED brushing their teeth with this. They had been fighting to let us brush for a while, so it was nice to find something they liked. My husband and I have been using the mint flavor, and it’s been good as well. We like the ingredients, and the texture is nice. The tubes both felt like they could have fit more, so I took off a star for size/value.

Very effective!
Size: 4 Ounce (Pack of 1), Set name: A. Strawberry Mango
I switched my son to this toothpaste and it has been great! I haven’t noticed whitening, but his teeth do look good and clean after he has brushed. He loves the flavor. And he is one to complain about “spicy” toothpaste. This toothpaste has never been whined about in my household. In fact, switching to this toothpaste has made brushing his teeth simpler because he enjoys the flavor so much. I have noticed it doesn’t foam up like other toothpaste’s do.
Another side story, and probably the biggest thing, I think this is actually shrinking my sons cavities. His pediatric dentist told me he would need fillings before his teeth could fall out at 12 (12 year molars). I saw the cavities on the xrays. A year later, the cavities are smaller. And the dentist said if things can maintain this way, there will be no need for fillings! He does brush morning and night, and often after lunch because we homeschool and he has that ability. But I’m just thrilled that my son could potentially avoid this procedure!
