[Q]: This adapter is the best one I've come across for plugging in US devices to European two pronged ROUND plugs (be aware-Switzerland uses smaller two pronged adapters). It is really well constructed- not flimsy like many I've used before. The additional USB plugs made it perfect for charging phone and e-reader along with computer. Not the smallest, but it is worth having something that doesn't spark or break in half! Will buy again!

[Q]: Worked for a few hours then would stop working and you'd have to unplug it from the wall and plug it in again. Just for it to stop working 10 minutes later.

[Q]: That sort of thing needs to be in the description, or clearly readable in the photos, or at the very least, in a downloadable MSDS sheet. But none of those things are available for this item. People (such as myself) looking to restore/improve their cast iron cookware have no way of knowing in advance it's not safe to use this on things that make direct contact with food. I might keep it for some future cleaning need, but I can't use this for cleaning the crud off of a cast iron skillet that is intended to be used for cooking. It might be great for cleaning things that you don't cook food in, but i have nothing like that to use it for right now, so I can't evaluate it for that purpose. The way that vital safety information like is presented (or isn't presented in this case) to the consumer before purchase is definitely part of what makes up a product, and is a valid point for judging a product's quality.
