The only thing I've found about pricing is in the youtube video at link below at 13 mins in. Starter kit is said to be £2940 for the eversense xl which lasts 180 days. So that's erm, deep breath, £490 per month... Plus £500 insertion fee to the doctor. And it sounds like that involves a trip to London as there's currently only one doc trained to insert.
Then £1540 for each new sensor, so £256 per month. Plus another £500 for the doctor.
I was quite interested in it from the point of view that if I was to head off backpacking for a few months, it would save the hassle of carting lots of libre boxes around with me, but at the reported prices, sorry, no.
Also, a common T1 complication is slow wound healing, so I'm not sure they've thought through the implications of cutting a large hole in the arm. Don't watch the insertion video linked below if you're squeamish! It's like Hannibal Lecter developed an interest in cgm...
@Jollymon makes a good point about what happens if it's a bad sensor. Libre, fine, rip it off, attach a new one. Eversense, another trip to London.
All in all, good idea, but ahead of its time.
