I have 2 kits on My Heritage. One is an Ancestry transfer from this time last year, taking advantage of their free tools forever offer. This was well worth doing although it has not generated a huge number of helpful matches . ( I do also wonder about my having a match with Gideon Japhet, the father of the founder of MH!)
Earlier this year in a moment of weakness and out of curiosity I decided to take My Heritage's own test. ( It seems to be permanently on offer). Without a sub I only have access to one shared match per match and so rarely bother to look at that kit's matches.
