I always consider customer service to be the most important factor when choosing a product and this especially applies with an ISP. Vispa so far have been very fast to respond and very helpful.
Setting up was a breeze. There were some teething problems with line speed which I was told were due to line calibration period. Today I noticed a huge speed increase and will see if this continues. The only other problem was some minor clitches on forum registration.
So, so far so good and pleased I have chosen Vispa over some of the other providers who spin a good sales pitch, but never really deliver.
