Those do not fit a Makita Router. This is what an ER adapter is. 
I think he means that the ER11 collet (by luck) fits in the Makita like a ”normal” collet would. Since I have allready ordered a 1/8” collet from Elaire, this is not for me but hopefully interesting for others to know!
These are ER11 collets! 
They require an ER Clamping Nuts in order to function correctly…
My understanding is that these clamping nuts do NOT fit the Makita and without the proper clamping nuts the collets will not work correctly.
Maybe I’m wrong but I don’t think so or others would be using ER11 collets.
See the post I linked above. I’ve been using them for a while with the original collet nut. They don’t look like they should work, and they shouldn’t work, but they do.
