June 21, 2025 A Watertown, SD Customer
ITC Fiber
February 11, 2025 I'm a new customer for ITC, only having used them for about 2 months. Previously we had a long range wireless company named GigFire as a provider. They were utterly horrible. The install with ITC went well, although they are not good at communicating plans to customers during that process. Staff was great and they knew their jobs well and other than me finding everything out last minute, it went smoothly. The services is great so far but I'm not impressed with paying $80 per month for 250mb when other parts of the world have gig fiber available for less. This is doubly frustrating knowing that the fiber infrastructure buildout where I live was paid for entirely by a federal grant, not the provider. It feels a bit like price gouging but I guess that's the norm in the USA. Overall, I'm satisfied with the service and provider.

Bluepeak Fiber
September 06, 2024 I switched to Bluepeak from Midco because they were offering a great deal for much lower monthly prices. The speed is really fast and similar to what I have had before. The installation was easy and did not take too long. They have a phone app called eero which is really helpful to look at internet activity and change settings. The only thing I do not like is sometimes the connection and speed is not stable so I have to reset the router.
