This is another opinion, without assessing whether one is better/worse than the other.
I have no experience with DGX (5 or 6), but with free 1 and free 2. true that everyone who uses DG talks about its precision.But for me it is also important (a) the cost per year and (b) that is "minimalist.
I discarded the DG in its day because it seemed a mess to have to change the BT Issuer after having paid it and quite expensive, and that the combination of sensor and emitter is so "big" (I know it is not so much, but for me it is).
On the other hand: with free (1 or 2) an issuer like Miaomiao and an app like XDrip I have options similar to those commented by @jldiazdel: you can calibrate to improve precision (they worked well for me in terms of precision, knowing how to calibrate whenIt must, when flat).It detects well up and down of HC as @jldiazdel comments, after 10-15 minutes ... In fact, I have proven that even with glucose gel the time it takes to react the body (HC absorption) is around that time.I did not observe that there is that delay, except when I use direct connection between the ProudLink APP and XDRIP (the algorithm makes it a slow to follow the ups/down), but it improves a lot if the XDRIP app is used with direct to free connection2 andIn the background, the small OOP2 app to be able to calibrate (it is an inverse engineering app that transforms the direct reading of the sensor sent by the appthlated app into gross values and these in values calculated depending on calibrations).
I also leave the mobile in plane mode connected by BT and the program warns if there are ups/down.
Therefore, several of the supposed advantages of DGX do not seem to be exclusive to the system.
Of course, as you say, it's a matter of taste.But my economy does not give for DGX.Of course, almost all laboratories have their things to "fall" and "loyalty."It is well known that the DG5 could be extended in duration (some up to 100 days or more, if I remember correctly) but the emitter BT could not extend, or something like that .... how easy it would be to recharge the battery and not haveWhat to change it.
In my case, I could extend the free1 with an app designed to restart it at 0 days, and I got to extend some to 20-25 days, but it was already noted that from the 20th it began to go to less (the gross data were veryLow until I saw, it became almost 0 constant ...)
If the cost was another, I would have fewer doubts.So envy you give me, @jldiazdel
