Are power-line Ethernet adapters any good?

Just so you know I not very tech savvy but a figure you guys might know about such things. I want a more stable connection for next gen and at the moment I'm using a wireless router but on a regular basis my internet cuts out and these adapters seem like a good cheap way of getting around this.

What do you guys think, am I just being naive or is this a viable option.

Thanks in advance.

This video should answer your questions. In short powerline > wireless.

A hard-line connection will always be better than wireless connection (for now), at least more reliable when it comes to maintaining a stable connection. Signal strength is another story.

My housemate set up part of our network with power line Ethernet adapters. We've got my desktop and his Raspberry Pi hooked up with them. They work pretty well.

I've used them before. Work without a hitch, good bandwidth and latency. Go for it!
