As we all know, extreme care must be exerted when purchasing Tefillin and Mezuzot. Many people (especially from חו"ל) buy at specific emporia in Meah Shearim and Geulah, often assuming that if we order Tefillin with all the Hiddurim, that that is what we'll get.
Today, I encountered a case where a pair of tefillin which were specially ordered were barely kosher, and the Sofer who checked them informed me that the ktav was an obvious case of 'get it over with minimally, who cares about the person who wears them.' In this case, the parshiyyot were written in a mishmash of Bes Yosef and Ksav Ari. The tefillin fetched good money, needless to say.
They were purchased at HaMeyfitz at 70 Meah Shearim Street, which had been known for being a bit cheaper for Gasos Tefillin than the competition. Obviously, you get what you pay for.
There are many upstanding Sofrim in Israel (and I can recommend more than a few. Noone should buy into the 'it's Merah Shearim and the Sofer is a Hassid/has a long beard/looks right therefore reliable' trap.
Anyway, HaMeyfitz should not be trusted.
