Obviously, you did, and maybe people would have had a different thought about the whole thing. Still, anyway, it is nice you realize the situation now, maybe if someone who has used their services vouches for them here, it could be nice. Still, as it is now, nobody has said anything about or on using their services here except on trustpilot which means that we can only say something about their services if only we use it ourselves but doing such would likely mean we defying all odds to using their services, maybe trust could come in play for the time being and see how it goes.

Funny enough, for you to test their service, you must have to have forgotten and lost the access to your wallet and in recent time, no one wants to intentionally throw away the access to their wallet simply because they want to try out a recovery service without no backup.
These work might get tiring for them if they don’t do or spend more on building reputation and publicity because that’s the two major things they need to be able to scale through in the industry.
Regardless of all said, having to show people  on here the result of their previous works will go a very long way to build and give a head way to trust and I will suggest they show their previous works on here.

I think you stated clear points, personally I wouldn't know if there services are good , just as you said someone who had make use of their services can actually tell us how good it is, in this forum, irrespective of the service we need, we should be extremely careful, it is not adviseable for a time to just go into conclusions because may be we have been looking for this kind of services, nah nah, in all this, it is a perfect idea for us to atleast take some precautionary steps for safety reasons.

I think that this is a great idea, if we can get a few reputable members in this forum that has used their services before, it would be pleasant to hear from them how their experience was, if keychainx is as effective in recovering lost asset as they claimed, because when looking at review, some people may be  saying different things, even though the positive things are greater, you will still be skeptical about it, but if you are hearing of the experience of a few reputable members of this forum when they tried to use their services, you will be certain that you are making the right decision if you have a job at hand that you know they are capable off, but as for now, their is no 100% guarantee that they can do it and their is also no assurance that your asset is safe with them, so they needs to do more in building trust and confidence between them and their clients.
