The thing with the .io hype is that only a handful of good flips have given the reputation that it is an amazing market .. when in fact the number of sales truly isn't that staggering.
Also note that sales are virtually non-existent for keywords outside of tech .. unless maybe the words make for a cool brandable .. wihch is not the case here.
The only thing keeping this from being truly worthless is that the keywords are extremely strong .. but because they don't match the TLD I think you'll have a very very hard time selling this for anything more than a couple of hundred dollars. Even then it'll likely be to another domainer who doesn't understand the .io market.
