Anyone having an issue with Fluke cases getting brittle? I have a 177 that had the battery cover crack in the screw boss area, and the other side won\'t hold a screw as the inside post is cracked. The plastic is brittle and reminds me of the aging of plastic in 1990s plastic television cabinets. My 85s never did this and I have a very old 77 that is still in perfect shape although it doesn\'t get a of use. The 177 is my daily meter and yes, it\'s fallen a few times.
