Do not buy this ELD device. I think the device itself may be ok, but it's functional dependency on this ridiculous app cripples it to the point of utter uselessness. It worked ok for a couple days, then it will not connect to the internet. And when I say worked "ok" I mean just the connectivity part. The experience through TransfloHOS is terrible, difficult to edit, and just not put together or thought out very well in general. It should be a very simple, straightforward app that is quick and easy to use, this is far from that.
I thought I would check the connection by using other features in TransfloHOS such as the tutorial videos. They all load and play, fast and with no delay at all. Yet the log management part within the very same app says it can't complete a simple data transfer due to poor internet connectivity, even though it can seamlessly stream video with no issue, which of course requires much faster transfer speeds. I can't speak to the quality of customer support as I have not contacted them. With so many customers using this system and it still not working properly, that says all I need to know. I'll write this one off and try a different ELD.
