Yes it's available in UK but trying to get 1 on prescription is not easy. I ended up asking my pharmacy to order 1 for me and I paid £38 for it.
It's very similar to the previous echo pen but the display end of the pen is slightly larger and the display shows the dose and a count up timer since last use in hours, minutes and seconds and is very clear which is much better than the old 1 hour time blocks.
You can also upload the data to an app to see the last few weeks worth of injections which I use to investigate unexpected highs or lows, just to make sure I gave myself the correct dose.
Overall I like it a lot.
