Well it looks like my constant pestering of the wife just payed off. I got her to let me get a new one a C2. I hope to have it by next weekend.
My C2 has the number L52 on the razor and no number on the box. BTW, the spreadsheet says the number is on the inside of the blade door. Mine is on the inside of the tray door that swings free when you pull it out. @Misphit check this door rather than the one marked "blade". You might find it there.. @Darkbulb Please update the spreadsheet for me. Thank you.
It's been 'cloud deployed' now so everyone have access to it to make their updates (Btw, nice score!)
Ah, I think you might need to have the Google Sheets app installed. Not sure. Thanks @twhite I do wonder if there ever will be some pattern emerging....
I have Google Sheets. When I click on your link the iPad just asks me if I want to download Google Sheets even though I already have it.
yeah I do remember it being a pain on the iPad when modifying an existing s/sheet.... sorry, making it a google s/sheet was the easiest solution
