I've traveled extensively and used dozens of different adapters over the years. I've found I love the Ceptics brand adapters because they're sturdy and easy to use. Most adapters have the multi-input plugs which are often a pain to use, but these are special-purpose for US electrical plugs. That keeps the plugs in tight rather than flopping around in a not-quite-right-for-any-plug plug. Plus having the second plug opening on the side is a great bonus. We purchased both standard European and Italian adapters and both have worked perfectly.
