[Q]: This small vacuum cleaner is really powerful enough to clean the dirt / food particles in car. Cleans well even in the small gaps between seats. The long pipe accessory makes it easy to clean below seats. This works well even without the car engine off in my crossover. And the long cable helps clean inside as well as outside the car. The filter is easy to remove and clean. A must have item.
[A]: positive


[Q]: I like these stair for my chi, he is only 5 pounds and this stair is easy for him to climb. plus they can easily be carried to my motorhome so he can get on the bed.
[A]: positive


[Q]: I like that the color can be extra small and extra large to fit all stages. I do not use the shocking component but the beep and the vibration mode are enough to distract my dog from what she is doing that needs correction. The double charger is really nice! So far I've only had to charge the collar and remote once.
[A]:
positive
