I have some. I don't use them often, but they are very useful on
occasion (when you want to insert a sampling port in coax with
minimal disturbance to the line). You normally use them with 10x
probes to minimize the capacitive loading at the sampling port. They
used to appear on eBay quite frequently for $2-$5 each, but for the
last year or so sellers seem to be very proud of them.
Note that you need one that matches your probe tip (5 mm, 3.5 mm, or
2.5 mm ground sleeve).
Best regards,
Charles
