[EX Q]: 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.
[EX A]: positive

[EX Q]: Sorry but I didn't find this helpful at all. It provided non valuable minimal repetitive information and was about 4 thin pages. I'll do my own research trial and error in the Hope's I can get some positive credit union results.
[EX A]: negative

[EX Q]: Easy to install, fast delivery. Clear tone, not too loud, but just right. I got it to put on a knee scooter that I borrowed from my niece when I broke my foot. It's a fun little bell, and they'll get a laugh when I return the scooter with a bell on it.
[EX A]:
positive
