I can’t say that it is all that bad but it is very flaky. Download sometime don’t start or abort abruptly and they don’t remember all the megabytes downloaded. They restart again from scratch. Eventually, after few retries, you get it.
Still this one doesn’t work. I am not sure from where I am downloading that stuff since it is a third party, Microsoft or CloudSurf. Any way I sent them an email (cloudsurf) to see what they say.
