Overall I would recommend them too, but in recent months I have found an increasing number of time wasters, and I don't mean the usual people who don't read what you are looking for, I mean people who appear serious, you exchange messages, make a booking and then they let you down on the day having confirmed already.
I have had several people who didn't bother to check the distance before they set off, and when push came to shove they weren't prepared to make the journey, and more than one who claimed to have overslept on the day (in all those cases, of course it's very short notice to try to make alternative arrangements). So I'm becoming less of a fan of them than I used to be.
