Can I check a Mezuzah myself I’m just looking for breaks in the word right?
There many things that would render a mezuzah unfit. Best to send to a reliable sofer.
-I’ll list just a few examples.
Obviously all the words have to be spelled correctly and in the correct order (Yup I have seen some disasters)
Coloring is off.
While not making the mezuzah invalid it is nevertheless telling if the crowns are missing.
The authenticity of the klaff
to name just a few…
