Review on Ceptics European Travel Plug Adapter CT-9C - Universal Power Adaptor Charger - Dual Input, Ultra Compact & Lightweight - Compatible with Type C Countries: Italy, Iceland, Austria, and More (White) by Shawn Schmidt

Used in Iceland, Scotland and Ireland in 2016 with no problems. Although sockets in these countries sometimes gave the impression that they were not compatible, this product fit like a glove every time. Power User Tip: If you can't insert a plug into a seemingly compatible outlet, try inserting the plug at an angle (e.g., insert the left side first and then the right side, or vice versa). . And if you run into resistance, you're probably using an outlet with a built-in safety feature that you have to manually "override" by opening the hidden valves at the top of the outlet (using the pins on a plug). while gently guiding the other connector from below. Works like a charm every time. Please do not let children try this advanced technique.
