The local DSL connection sort of works and we sort of get a cellular data service at our new home in rural New Mexico. The Balance 20X lets us put the two together to get usable Internet. Given the large number of features, I was concerned that the setup would be difficult and time consuming. It did take a bit of detective work to figure out that even the unit was brand new, the firmware was old and need updating. Once that was done, configuring Speed Fusion Cloud took just a few minutes. With the default settings the fused download bandwidth has not gone up much (if at all) but the connection latency is significantly lower. And most important of all, the upload speeds, which are terrible with DSL, are now comparable to my download speeds. This makes Zoom usable and working from home a reality.
I have no doubt I can squeeze better performance out of my two connections (Windstream DSL and Verizon Wireless). But since this is in reality a commercial grade unit it will mean digging into the documentation and getting schooled on router software. And while we are using a separate cell booster to improve our Verizon signal, at some point I may try an outside external antenna.
What I like most about the unit is its flexibility (we're on the waiting list for Starlink service) and that we can try different combinations of connections.
