Review on Kreg DECKSPACER-RED Deck Jig Spacer Rings 1/4-Inch, Red, 12 Pack: Perfect for Precise Deck Installation by Yoganand Stradley

The only thing I would change is the color of the top handle if I'm making a huge deck and in a hurry I usually turn them upside down here and there, I put tape on my to make it easier to notice my mistake. I also use normal old plastic shims so that I can adjust the spacing of the boards in the long term if necessary or between transitions etc. easy compressibility which probably doesn't bother a mountain of beans they grip quickly, don't fall through, don't compress Good to have and for simple basic runs and then to use some other tools if necessary.
