I don't know how some it works great since it is not physically possible. The diameter of the blade holder is smaller than than a Maker holder and the entire length and depth of the holder is wrong for the Maker. It is not even a close fit....had to order a different one and THAT one is identical in size and diameter to the normal Maker blade holder
THESE DO NOT FIT THE EXPLORER AIR, IT IS TO SMALL. WHEN YOU PULL THE OLD ONE OUT TO REPLACE IT, YOU HAVE TO UNLATCH IT. WITH THIS ONE, YOU CAN LATCH IT BACK AND PUT IT IN AND IT WIGGLES AROUND, ITS NOT THE RIGHT SIZE OR DESIGN, WHATEVER YOU WANT TO CALL IT, IT WONT WORK.
