DIY Reliability of built on frame power grid

[tommyjw6206]

I'm considering using the power grid built on to a Tarot 680 frame but am so un-trusting of those connections. If the solder joint is real good, has anyone had good/bad experiences with those connections?

Those look interesting, have not tried them though.
