I used have Apollo and I am now using Voyager, Voyager is by-far a superior product in every way you look.
1)Voyager is way smaller than Apollo. 2)Voyager doesnt have removable battery Apollo does. And that is probably how Infomark (the maker of Voyager) was able to shrink Voyager to this size. 3)Voyager doesnt emit heat like Apollo. 4)Voyager has better speed than Apollo and unlike Apollo no data connection drops for 5-days of use. Apollo is a good product but Voyager is just a superior product.
The only problem I personally have with Voyager is that I couldnt change the default IP address from 192.168.1.1. to 192.168.x.x. I hope next time Clear or Infomark make some software/firmware update they will make this configuration available.
1) Smaller footprint 2) no-longer device & battery connection worries during troubleshooting. Sometimes Apollo will not power off unless you physically remove the battery.
