Picking a Norelco trimmer is a nightmare... Is this the one? -- 9000 "Ultimate"

There's the 7000, the Costco one, and seemingly countless 9000 series ones.

But Amazon has a sale on a 9000 "Ultimate" (I guess the model is "BT9810/40"?) that's pitched as a "beard trimmer" and has a spinning dial in the handle instead of two dozen attachments. Attractive. It says it's steel.

I use a trimmer multiple times a week usually, and like it to go close if possible since I never shave and am prone to razor burns.

Seems like this fits the bill, but I'm curious because the scene seems to change every year or two with crazy model spinoffs and Norelco swapping in plastic parts. Thanks for any info
