Base is OK. I saw a part of the video painfx (OP) posted about the Ultra's leaf spring possibly getting loose. One should shake their new Ultra to see if its already gotten loose before putting it on. Then when on, as long as a big rock doesn't hit it, no problem. It does look like it is capable of getting out of alignment & loose up there.
From another bitog thread on the "rattle" problem sometimes seen:

You probably know, but I'll point out for anyone who doesn't, impact on the dome end of a spin-on filter can easily ruin it even if there's no dent or distortion of the surface. Excessive acceleration can permanently deform the spring. When that happens, the other internal components are no longer clamped together, which allows oil to bypass around the end of the media. I used to slap the dome end of filters with my bare hand, in order to more thoroughly drain them. Once I whacked a Purolator too hard. I noticed it rattled thereafter when shaken, and realized what I'd done, even though the can was undamaged. Therefore, I (sadly) discarded it instead of reinstalling it.

Yep, I've run into this problem with other filters as well. The Hyundai OEM filter (which has a thick, heavy can) that I received in the mail with a dent on the dome end rattled when I shook it. I came across a Mobil 1 EP filter at AAP that had a dent on the dome end and had the same problem. An employee placed the filter aside behind the counter and put a note on it so it wouldn't get put back on the shelf. Once I dropped a Purolator filter of mine still in the box on concrete, which dented the dome end and caused a rattle on the inside. Also, the rattle may not happen until later, after the filter has been installed and in use for a while. An impact on a hard floor/concrete surface and a dent on the dome end can cause a problem with the spring over time, with failure occurring after the filter has been in use for a while. There was an example of this on BITOG in the past. Dented filters should never be installed because it can lead to problems down the road.
