Is my Brymen BM235 multimeter faulty?

[Brumby]

Oh of course, sorry. I forgot... this is what REALLY happened...
As I was watching a video about how great Trump would be as President... I got sent a video about adding a 3.5mm headphone jack to the iPhone 7...
So I thought that could work on the BM235... so I used a 6.5mm (I only have the big headphone plugs) drill bit, but it went right through the case and into the PCB.
So I filled it with carbon dust from a lead pencil to stop everything from rattling and making a noise. Topped it off with some wood glue.
Still covered under warranty right?

What the hell is this. 

You don't get out much, do you?

As mentioned above - it was a joke ... A piece of fiction generated for our amusement at the prompting of another member.  A piece of fiction that I found quite entertaining - having drawn in a number of contemporary topics of bemusement in themselves.  I felt the OP had some skills and, perhaps, an aptitude for writing as an alternate vocation.
