that's the coolest innovation I've seen for wire connections. My only concern is how strong the connection is, can it be easily pulled apart?

Here's another brand on Amazon Prime for about 1/3 the price, and free shipping

$13 for 50 butt connectors

Those things have been around forever - we used them when I was working at Convair back in the late 80's. I have a couple of handfulls of them in a drawer, and they do work. Only caviat being is you need a heat gun that is capable of 800 degrees...

They look good. For me soldering is really easy, as it using a heat gun on marine grade shrink tubing so I will probably stick with that but for non DIYers these are great.
