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 Tim Springer

Updated: This product fits the South Korean socket very loosely. It's very easy to remove, so it's difficult to hold while charging electronics. It works, but I wouldn't recommend using it in South Korea. (Video has been attached to help you understand.) Personal Experience: All 3 adapters are in good condition. A phone charger and a 3 pin laptop charger are perfect. I am very happy with how they match the chargers. Since my trip outside of the US hasn't started yet, I haven't had a chance to use it, so I've given it 4 stars. It will be updated after I actually use them. Otherwise it looks great to me. Pros: - Ideal for chargers (not shaky or unstable at all) - (more details will be updated after a few months) Cons: - Not yet - (Needs to be updated after several months of use)
