As a result I have been looking into satellite broadband providers and specifically Tooway, however all of the recent reviews are very poor and mention terrible up/down speeds. Is this because only the unhappy people write reviews or is this generally indicative of the poor service?
I think with Satellite it depends if you start from a realistic starting point. The reality is that if you think you'll get a Fibre Speed, Unlimited Service... you'll be disappointed.
If you think you'll get a basic internet access service at a reasonable speed which lets you use more demanding services a little, you might be happier.
