Maye Bechtelar's review of Blume Global
Bottom line: pricey, but worth it if you care about real ETAs. I paid more than other trackers, but the predictive ETA alert once flagged a transfer delay and I avoided a $600 fee - definately paid for itself that month. After 7 years running in the Northeast I still gripe about subscriptions, but that one feature kept me from losing money so i'm happy.
