Features Direct replacement for factory 28mm festoon bulb Adds more modern LED appearance Plug and play simple installation Overview Design. The 28mm SMF2 LED bulb is a direct replacement for any 28mm-size bulb commonly found in vanity mirror lights in many vehicles. Populated with two 5050-size SMDs the SMF2 upgrades the factory yellowish incandescent bulb to a more modern LED appearance while adding far more total light output than the factory bulb. The SMF2 was designed with an embedded load resistor and implanted diode for superior reliability. With its durable metal terminals it will fit snugly in the socket and its light weight means it won't vibrate loose over time. Reliability. Unlike other bulbs on the market this bulb is built with constant-current circuitry along with transient suppression. That means this bulb will last for years not months with no flickering or failure. And like every Diode Dynamics product it's backed by an industry-leading three-year replacement warranty. Brightness. With 24 lumens of true measured output the SMF2 LED will provide about double the total light compared to your original 28mm-sized bulb. All Diode Dynamics LED lighting is rated with accurate measured lumen figures not calculations or guesses. We test the true output in-house and provide you the real numbers to compare. Colors. In addition to vibrant colors of blue red amber and green the SMF2 is available in a cool white 6000K and warm white 3000K option as well. Whether you want a modern cool white appearance or a traditional warm white color we have the color to fit your need!Installation Instructions

Lasted less than 60 seconds - 6 month puppy.
Flavor Name: Peanut Butter, Size: 4 Ounce (Pack of 1)
Lasted less than 60 seconds ! Stop calling a product a chew. When there is nothing lasting.
I should start returning products that are misrepresented. And stop reading reviews.

Great product
Oh my God, my dogs love these they inhale them, but I only give them one a day or even one every other day. It's perfect. It doesn't have ingredients in it that my dogs are allergic to like 99% of the treats and dog food have it so that's this is gonna be a definitely definitely thing that I'm gonna purchase for them.
My dog is allergic to furrous sulfate and why people put this in their animals foods I don't know, but they need to stop really putting things in it that doesn't really be necessary. This is great has nothing in it so hundred percent matter fact I'm reading it right now. It was for small dogs, medium dogs and large dogs. Well my dog's 130 pounds. The other one is 190 you cannot give this to puppies under three months old I don't know why but one thing is the package itself doesn't save the ingredients. Maybe this is it biscuit chicken coconut, peanut butter, some kind of starch and sorbitol, but it's only 2% so it's not bad but that is unnecessary to put in any Dog or cat for that matters.
