A lot of reviewers complain about the price. FWIW I got them on sale here for a good sale price. As far as that goes, to get this feature your other options are a Neo 3M or Kickr Move which are substantially more $. I think it's great that Garmin made retrofit for Neo1/2/2T trainers. Yes you can get rocker plate, but that is really big and can be costly too
As far as how they are, in the saddle it's pretty subtle and good. Adds to the "not being bolted to the floor" feeling. I do not like it AT ALL out of the saddle. Too much back and forth motion. I can't see how anyone would like it. My indoor bike is rim brake. I set the front brake so the quick release is set very tight. If I close it, it stops the front wheel which stops the motion. If I am out of saddle just a little I just grab the front brake lever
This really improves your engagement with Zwift. You pay much more attention to the twists and turns of the road, making the experience more immersive. I also run Zwift Sauce in order to see the drafting meter, and combined with the Sterzo, I am much more deeply engaged in my Zwift rides. I also have the Zwift play controllers that allow steering, but their approach is nowhere near as intuitive as this. I also have to give a shout-out to Sterzo customer support. A spring broke on my Sterzo after a couple of years of use. I contacted them for a replacement spring, and they sent me a whole new unit. Bluetooth connection is rock solid.
After 6 years and 20K+ miles I decided to replace my Neo2 with a 3M. Other than replacing the freehub my Neo2 was trouble free and I gave it to a friend. I have a little over 1K miles on the 3M. It seems a little smoother than the Neo2. I like the motor driven flywheel of the Neos, seems more natural when going down hill. The build quality of the 3M seems good and so far I am happy with it. Everything works as advertised. I had been looking at the 3M for about a year and decided to buy one now that the price has dropped.
You're probably fine without these, but the motion plates make the trainer better to use. And regardless of how poor of a value it is to pay over $200 for some plastic feet for your trainer, you'll most likely never want to ride without them once you set them up. They make the experience on my 2T a lot more enjoyable. To be frank, I think my nether regions hurt less with these installed. My biggest gripe is that they are only connected by some relatively weak magnets and will fall off easily if you try to move or fold the trainer with them on. I've also seen reviews saying they don't do well for sprinting...haven't tried it personally, but I've done some standing efforts on hill climbs and they do just fine.
