Review on 100PCS 16-14AWG AIRIC Heat Shrink Spade Connectors Male & Female Waterproof Terminals Kit 0.250"(1/4) Wire Connectors, Ga16-14 by Leo Black

The only 2 griefs I had with these, is the heatshrink extends over the end of the terminal connector and will shrink such that you can't plug the damn things in. I eventually learned to trim the business end back a little and to not heat that part so much. Now, if you plugged these in BEFORE heating them, they would lock in and work quite well, which may be what they were intended for. And I'm not sure wire sizing is the same around the world. Using my Kline crimper, I had to go down a size to get a good crimp. Not the end of the world, just be sure to tug on them and make sure your joint is solid. Good enough for the money imo.
