Got one myself, an improvement over the huawei stick:
I’m about 650m from the tower with no line of sight.
Getting stats and locking bands on the stock firmware needs a little bit of effort, pawol over at the eko.one forums has some javascript that apparently works as a chrome bookmark

Anything more requires a serial connection.
The speed test above is with CA on band 1 & 20 with 20 as the primary band, with band 1 I only get 2-5mbit upload, which the modem seems to default to.
I have tried setting 20 as the primary band all the time by locking to that cell, but when I do I the modem stops aggregating with band 1. On the eko.one forums locking to a cell is reported to set that as the primary and still allow CA:
https://eko.one.pl/forum/viewtopic.php?pid=258150#p258150.
I’m thinking about updating the software on the actual modem (the qualcomm based mini pcie card) to see if I can get the behaviour reported in the link. The unit I have is Three branded and shows its firmware version as HGGBMF286DV1.0.0B04, its auto update claims no newer is available, but firmware ending in B06-B11 seems to be around from other providers. Apparently the procedure involves using adb to push sequential updates to the modem card as detailed in the link here
https://eko.one.pl/forum/viewtopic.php?pid=271304#p271304.
Have not tried openwrt yet as without changing software on the actual modem I’d still have the problem of low upload with band 1 as primary.
