The switches work great, the only problem is the diameter of the post is a little Bigger than the old ones so I had to drill them out. But they work fine and they look good.

Just got the 5 amp units and tested 1 with a dead short and it Never popped. Smoke and melted toxins galore. These could burn your House/Shop down!

These circuit breakers are nice and small making sure that you can make a compact circuit breaker panel that does not take up too much space. Just drill a 10mm (0.4”) hole and insert the breaker and tighten down the nylon nut. When you are spacing the holes please note that the nylon nuts are significantly wider than the actual breaker. Also note that, like most circuit breakers, they are polarized. The incoming voltage goes to the ‘Line’ pin and the outgoing voltage goes to the ‘Load’ pin. If you hook them up backwards, they will not work.

These seem well made. But you can't really know if they work as intended until they either trip at a known current. Or they do not. So looks and features are about all I can go by.I would have liked dust caps to keep occasional moisture out. But I knew they did not have them when I ordered them. I will look to purchase those separately.They are easy enough to install and use. There are markings for Line and Load terminals. And they have push on male spade connectors, so they are easy to connect. They have plastic threads, so they may strip if you over tighten the nuts. But that will be the case with any similar units.

These thermal fuses seem reliable. They do pop at a constant >12A load but a 10.3A load it does not. They are not fast fuses so it can allow a inrush current significantly higher than 12A to happen which is a typical thing for thermal, resettable, fuses.I like this package since it includes everything needed to connect up to it. When replacing pre-existing locations with these all should be good for tolerances. With DIY or new applications some information is needed to ensure safety.With the applied dust cover the fuse pops out to a total length of 14.8mm (5.57mm from the top). When attaching the dust cover if the gauge plate the fuse goes through is not thick enough you could risk the fuse getting stuck closed. Doing some measurements and dry-fitting it looks like 3mm thickness is required to ensure a full pop.The included fastener is 3.24mm which could act as a spacer but adding a reasonable gauge steel box will make the dust cover more separated needing a slightly stronger push to reset. None the less the cover by self is very flexible and if threaded all the way to the end/top will still allow a proper reset.Dimensions are in attached image which can also be found online as these are typically standard sized items.
