Leviton make quality equipment and this one is no exception. But regulations sometimes tie manufacturers' hands or dictate design decisions for their products that can affect the product's usability, forcing them to pass the issue on to installers and consumers. not all) competitors who manufacture similar products. The materials used - from housings to contacts to brackets - are of the highest quality you'll find on the competition. Many apps seem to have so-called "tamper-proof" slots, ideally just keeping prying hands out of the way and not bothering the adult end-user. Knives or other similar tools in a jar out of curiosity. To be honest, the mechanism used does a good job of blocking such nonsense, as the design blocks foreign probe entry when only hot and neutral plugs are inserted at the same time. The downside, however, is that plugging it in is a real PITA until the socket is sufficiently worn (or a little "loose") and requires quite a bit of effort. And to be honest I personally wish it wasn't, but then again - I've never liked GFCI sockets which (IMO) nullified reliability and uptime due to their extreme sensitivity by repeatedly shutting them down prematurely. But since all manufacturers have to abide by the same code, I don't blame Leviton for that and I won't let him ruin this review. Overall this outlet is excellent and if chosen and installed correctly it will certainly do the job and provide years of trouble free performance. I recommend it.
