Kosiy Eiechip Set of 10 Power Resistor, Aluminum Shell Resistors, 25W 6 Ohm/8 Ohm, 50W 25 Ohm, 100W 8 Ohm/3 Ohm Watt Shell Power Aluminum Housed Case Wirewound Resistor for Nest Hello Doorbell

Works as described 👌

I haven't tried putting 100W through them yet, but it's didn't even get warm at 8W which is a good sign. The metal casing is electrically insulating and looks like it could dissipate a good bit of heat, especially if it gets mounted with some thermal paste on the back side, flush to another piece of aluminum. The casing is aluminum with enamel, which can be scratched off, so be careful if you need that part to be insulating. When I scratched some of the enamel, the casing was still electrically isolated from the resistor terminals which is reassuring to see. It's definitely as I expected for a product at this price.

well built, good value

arrived on time... As described... great product.... Thanks

I setup an outdoor projector screen with 8 ohm speakers on the sides of the screen, and 4 ohm speakers in the rear. I have a simple 2 channel stereo and wired left and right speaker pairs in series.The problem was that the rear 4 ohm speakers were louder than the front, so I used the 3 ohm 100 watt resisters from this product to put in parallel across the 4 ohm speakers and now the front speakers are slightly louder than the rear - exactly what I wanted to accomplish!

I needed a set of power resistors for load testing, and I needed a variety of resistances. This was a good mix.
