I currently have both the regular this app+and the HumX. Both of the products have made me feel safer for anyone driving my cars, and myself.
I love the ability to see my car’s health, and even track my trips.
I would highly recommend one of these products.. the only difference is the X does allow the WiFi (which is ok, but you have to remember you can go over your 1gig quickly, if you forget to turn it off) and the device looks more modern. The normal this app is definitely cheaper per month, since you are not paying $10 extra for the data plan. Quite honestly, I really should have got the second this app as a normal one, not the X, since I have tons of data on my phone. I was under the impression the Verizon data was CDMA, but it is GSM- my cellphone already has GSM, so kind of a waste, now- I wish I could switch it out, but can not, since under a contract, which I hate contracts.
In conclusion, it is an excellent product, which I feel very safe with (I live more out of the cities, and I drive about 36k miles a year, so this is a must if something ever happens to me. The only issue I have now, is the latest update to app has crashed a couple times, the tracking keeps freezing on about past days location, and the mpg does not work now.
