I'm somewhat skeptical of it because it isn't doing any sort of sustained testing. I have commercial internet access to my house (it's faster, I get static IP addresses, I can setup PTR records, I get 24/7 support with same day repair for the same price as residential, I just don't get discounts for bundling services) with 12mbps/2mbps sustained speeds. This test showed me getting 30mbps/5mbps, but it only ran for a few seconds, so it was only measuring my burst speeds.
