Not sure how to rate this as mine has came in last night and I believe it is broken! The “ lock and release “ feature is nonexistent the button I see in all the pictures is up even on the box but mine is not, even when I put my newly purchased coffee maker from Wayfair in it... it does not go up or “lock” in any way.  I will obviously notify them and see if it is in fact broken. But it looks otherwise like the photos, and I can roll the coffee maker in and out from under the cabinet. Which was the point of buying it.
