Query: Worked well so far, worth the investment

We bought this for moving to Europe to allow us to use our US appliances - we didn't want to have to invest in new ones. The transformer has worked just fine with our "high power" kitchen appliances like rice cooker and electric griddle. The picture shown is not what we got - actually the one we got is much nicer, with a circuit breaker and 4 output sockets: 2 US, 1 European and one UK. Two minor disappointments: the plug is US plug (should have been European, as shown, so we had to get an adapter), and the circuit breaker randomly trips at turn-on (not such a big deal, actually).
