No doubt their services may be good, but without someone with first hand experience to tell you how effective their service are we may never know until we try them out. I was even trying to check their reviews, they have more positive reviews than the negative reviews, which means everyone who have used their site gained different experience. At the end of the day, we have to be ensure safety because it is our asset that is at stake 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.
