I started by googling for the obvious: 2 day beard trimmer.
Based on the results, I refined it to: stubble trimmer.
The top results were typically reviews or "best" lists.
FWIW, I also googled for conair beard trimmer, which did produce results. Can't say if they match your current broken model, since you didn't specify what it was.
The search suggestions included "conair beard trimmer parts", so maybe there's something there you're willing to do.
This is all pretty elementary for Search Engine skills.
