These connectors worked for me, but I ran into a few issues. It comes from the weekend warrior; no electrician. First, and this isn't necessarily a problem with the product, but it's important for buyers to know: the hair dryer won't work; Period. We have a very high temperature, a strong one which I thought would work with a little patience; it didn't dent. I had to order a heat gun and use it on high settings to even start shrinking. So take this into account when doing the cost analysis. Second, I assumed the electrical connectors were standard sizes and I could trust the measurements given. Unfortunately, none of the yellow connectors fit into the ports on my PSU except for the spades, and there was almost no room for the connector's screw (since they're not really for that). I ended up not using the plugs, I plugged in a bare wire which made my purchase pointless. I measured the size of my PSU connectors at 3/8" and this kit includes 1/4" connectors, but that is the inside diameter; This may be standard, but I wish the description had something for beginners. But here's my big complaint: the wire sizes are wrong. I tried using the blue butt connector to connect 18 AWG wire to 22 AWG wire. They didn't fit. I had to use yellow to attach them. And I couldn't get my 10 AWG wire into the yellow butt joint at all. That caused me a big problem and set me back a bit. However, the connectors held up well after installation and the heat shrink tubing worked as expected. The shrink material felt strong and I had no issues with tearing. I was eventually able to get the job done (though without any connectors for my PSU.
