I guess the two things I think
of to complain about are that it doesn't tell me if reactance is L or C and
it's a battery eater (10 AAs). I try to minimize the use of mine on
battery power and wish changing batteries didn't involve removing the
cover. You should check them every 6 months to make sure they aren't
leaking.

Something I learned on these pages a few years ago: To save battery life on the -259's, insert a dummy 1/8 inch power plug into the receptacle while it's not in use. This totally disconnects the internal batteries from the set.
Also, to determine + or - J, increase the freq on the -259 a bit. If the reactance goes up with freq it's inductive. If it goes down with increasing freq, it's capacitive.
