Ok so an update.
I have a T2 Screwz kit.
Now lets pretend I was building a T2 and not a T2R.
I have 20+ extra screws and I am missing 5 screws I need.
Sorry to bring this all out in the public like this but this is a huge problem with your product that I have read on other forums.
You need to be aware of it and fix it.
If the screws are so cheap you can afford to give extras keep the extras and lower your prices.
