I really enjoy my EZLynk and I too have my tunes downloaded on a couple devices so that I am not relying on the cloud. With Trudeau spending most of his time in a cloud.. the last place I want my Cummins tunes is in a cloud waiting for the wrong commie to come along. I enjoy the feature of easily switching tunes with my app on my phone and the gauges on my phone if I ever feel like seeing them. I am running Optimal Welding tunes and am seriously considering switching to CCS after all the awesome reviews on here. The honest only reason I have not yet is the 5 or 6 reviews of saying that the CCS tunes ruined a transmission or was riddled with issues. Don't get me wrong, I know there are probably the same if not 10 times that about Optimal Welding but I just have not seen it and have not experienced much of anything wrong with the 5 tunes I have on the truck. Mind you I find myself running in stock setting more and more.
I remember seeing a comment or message of how CCS feels much more ''grown up'' than Optimal and I can see how that could ring true, as Optimal on my truck sure does cycle the VGT a bit and sometimes seems a bit hyper active (but this may be a good thing?). I am sure once I finish spending the money on my RTT and couple other overlanding stuff left that I will switch, but the more I think about it, the higher on my list of priorities it gets.
I apologize and know this was not the point of this thread as the OP said but it is my experience with EZLynk nonetheless.
