A beautiful set of international power converters for travel. It is equipped with international adapters for different countries. I am very satisfied with this product and will buy gifts for travel friends again.
positive

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.
positive

I bought this item for its portability during my trip to Iceland, but the one time I plugged it in (using a universal adaptor) and turned it on, it suddenly smelled like something was burning and made a pop sounds, then stopped working. What a waste of real estate in my already limited suitcase space. Didn't even get to use it once. Dangerous and worthless for my purposes.
