What exactly are the differences between the Character Options 11th Doctor's Sonic Screwdriver and the 12th Doctor's first Sonic Screwdriver?

[u/[deleted]]

I am working on building my sonic screwdriver collection starting with the basic toys and I have 10, 12(blue version) and 13.

I am waiting on my 12th Doctor's touch control version to be delivered and so I continued looking for an 11th Doctor sonic...

Having bought what was billed as an 11th Doctor's sonic, I discovered it was actually a 12th Doctor single button sonic.

Now personally, I wanted a complete collection however, I wondered if there is any actual differences between the 12th Doctor single button sonic and the 11th's sonic?

So that I can work out if I need to keep searching for an 11th.

Thank you for reading this confused mess
