I'm surprised I haven't seen any threads or comments about Boingo on FlyerTalk but does anyone here (still) use them and, if so, what do you think about them?

Since a lot of airports have free WiFi nowadays -- and you can get free WiFi at just about every airport lounge -- I don't see Boingo offered as much as I used to but I still run across a few places when I travel that require a Boingo login. In theory, with the number of hotspots Boingo has not only in the US but all over the world, a Boingo membership would seem to be worth it but recently I have been hearing a few complaints that Boingo service now "sucks". I was wondering if anyone here has had any recent experience with them, good or bad, and would they recommend signing up.

Also, I am thinking about switching to T-Mobile US and I understand that T-Mobile had some sort of partnership with Boingo. However, looking online and it seems that all the information is dated pre-2012. I am wondering if T-Mobile users can still signup for free Boingo service.

Any answers or information?
