OK so it does trends, and it's cheaper. Still if I had a kid I'd rather they use Dexcom especially during sleep. They only wake you up if you go below 75 (4.0) I think and maybe you can change to alert number.
Sure, if I had a T1 kid, I'd likely go for Dexcom or Medtronic because of the alarm, but the plain truth is that not everyone can afford those.
Pricing of Dexcom can work out similar to Libre but only if sensor life can be squeezed out longer than recommended by the makers and that doesn't work for everyone.
As it happens,
www.ambrosiasys.com is due to launch a libre transmitter at the end of April for a one-off cost of 110 dollars for their nightrider version. The main site doesn't say it but their twitter site says it will do low/high alerts - see post on March 20. If that's correct, and it actually works, then there's not going to be that much difference between libre and dexcom.

In the day time, no alerts on the libre aren't a problem at all.
Scanning is so easy it just becomes a habit. I've had quite a few situations where I scan, see the general direction it's going, see the downward arrow which appears when it reckons it's in the process of dropping rapidly, and I'll think about whether to have 5 or 10g. I've headed off plenty of possible hypos before they have even happened.
And take the occasional 1 or 2 u correction if it turns out my last bolus was underestimated, before it gets too high.
The general ability to steer it in a proactive way rather than responding once it's already too high or low makes strips feel like the Stone Age even without alerts.
Sure, night alerts would be great, but the reality is a lot of night hypos have their origins in what happened in the last few hours while awake, so being able to see what's going on before going to sleep provides a lot of steers.
It's made CGM available to a lot of people who wouldn't otherwise have it.
