Prone to what problems… guaranteed you've never actually tried Moca devices… ask the average Joe to pull Cat 6 throughout their house. How many you think will try? Pretty well every house has coax throughout their house. These MOCA devices use the existing RG6 to establish wired internet for those who do not have Ethernet cables throughout their house… or can't or won't wire their house with Ethernet.

Do research regarding MOCA standards… I use them to wire backhaul my ASUS ZenWIFI Pro ET-12's… I have ATT 2gb Fiber. I get over 2gb/s wired. My wireless speeds can reach around 1gb/s near my router that's wired backhauled via the MOCA device.
3W = 0.003 kW
0.003 kW/device * 2 (devices) * 24 (hours/day) * 365 (days/year) * 6 years = 315 kWh (for 6 years)
Average for US currently is 15.45 cents/kWh [energybot.com]:
315 kWh * 0.1545 $/kWh = $48.72

The max power the supply generates is 6 W, so it can be as much as double the above calculation, but usually supplies are over-spec'd, and assuming half the capacity (on average) seems a reasonable starting point.

So, yeah, you are spending a chunk of change on power as well. I can't conclude either way whether that cost is significant for each individual. Wholeheartedly agree, though, that maybe the $170 that one might spend is worth the effort of just pulling cat6 cable.
Veteran ISP network engineer with lots of MoCA experience here. I agree with everything you said with one exception: MoCA 2.5 is not a duplex communication system, it's still simplex ("half duplex") just like its predecessor versions and WiFi. We won't see duplex MoCA links until 3.0 hardware hits the market. The spec has been ratified but we're still waiting on MaxLinear to release chipsets so they can be embedded in next gen MoCA adapters. I'm looking forward to 10 Gbps symmetric throughput (probably more like 8.5 Gbps after error correction and other overhead just like XGS-PON) and don't mind the potentially shorter reach, much higher power consumption, and massive RF spectrum requirements that will likely come with it.

Does anyone know the range of a device like this? How long can you extend 2.5 gig ethernet over coax RG6?

Really annoying that they mixed the product reviews with their WiFi routers

Some Modems (eg from Xfinity) have a built in MOCA. You just have to turn it on in the Hardware settings… Therefore you would need only one.

If you're ok with crawling into tight spaces, just pull new CAT6 cables. Adapters like these just become prone to problems and eat phantom power. Calculate what the energy use is over 6 years. (3w (estimate per device) * 2 devices * 24 hours * 365 days * 6 years) / energy cost per kWh

It could very well end up like $120 extra for 6 years for the life of your setup. Not a whole lot but still.

I have attic space on the 3rd floor and a finished drywall basement, can you come show me what spaces I can crawl into so I can pull Cat 6? On the topic of moca adapters, I do use a different brand but they work flawlessly providing my full internet line speed of 1.3GB with little fuss. The only downside i have encountered is approximately 3ms of additional latency.

Maths are hard… I get it. But your equation there couldn't be more wrong 😉. You end up with Wh / $/kWh…
Please stop giving advice in forums… you're not helping anything.

Hint: 3W / 1000 gives you your kW, and you wanna multiply by $/kWh to get $.

$50 over 6 years vs pulling cat 6?
Definitely spend the $50. Unless the house is super open, unfinished basement, large attic, .etc.

Are these noticeably better than the Frontier FCA252 you can get on eBay for about $60 a pair (new)?
