oh man that’s a bummer. I have an older model and it does work… but only just kinda… it’s not what I would call “convenient” to use with an implant… maybe if the implant was on the knife edge of my hand or between pinky and ring metacarpals it would be easier… but I can confirm I can get it to work fairly reliably with my xEM… but to show just how difficult it can be, I recorded this video with a NExT in a tube with antiseptic solution… it takes very specific placement… and at a 45 degree angle which is unexpected.
If you cannot get it to work at all, I would consider a “safe swap”… I don’t use this except for demos.
