The biggest problem with them are that you have to make a PROPER crimp which requires a GOOD crimp tool.
Another problem is that it's a one time only connection. Make it and if you ever need to redo it you have to destroy it.
The strip I suggest (get GOOD quality not the Chinese rubbish that are in the 1 euro bins at the DIY store !)
can be cut to size (so 2 terminals only if needed etc.), and further you only need a screwdriver.
My suggestion is to twist two wires together and mount them from one side. Alternatively, twist the strands on each wire and tin them.
