I think you have to think very carefully about what you are and aren’t getting, and what you’re paying for it, and whether you’ll use it. There is a use case for each where it’s a way better choice. But I would approach giving a gift of something like the Mirror very carefully.
It’s like $1500 up front, and it’s just a mirror without the subscription, which is another $50 or so for every month you want it to be anything. If somebody is going to use it frequently enough to make that worth it, it’s a super cool thing to have around. You’re paying for a gym membership, effectively, on a monthly basis, and you get to do whatever classes you want whenever you want at home on your schedule (I think - I guess some of them are on a live schedule).
In my individual use case, though, I’m certain that I just wouldn’t use it enough. Having it just sitting there on the wall at home, as opposed to being a big old building that you drive to and park and walk through the door and swipe a membership card and say hello and go do your whole routine, would be I think in my case very counterproductive, because I could just… not do it, and keep sitting in this chair instead. There’s no routine there. It’s not different enough from just Youtube or exercise DVDs, or some fitness thing on the Switch, for me. In theory I could always find some trainer to put on a screen to tell me what to do, and do it. The same thing goes for Peloton, but at least that’s always a bike. It is always a thing sitting there saying hey exercise on me a little. So for me, Peloton would be better because I’d be more likely to do the thing you have to do to make it worth it.
So, I guess long story short: the Mirror if the user is the kind of person that really wants to do frequent high intensity workout classes, for sure. It’s way more versatile and cooler, in my opinion. Peloton if you definitely want to get one of them, but aren’t sure how much use it will get, because I think spin classes are a little more appealing-sounding when you aren’t doing them.
Competing products: if I had several thousand dollars and the housing setup to do it, I would get Tonal. The added option of resistance training, for me, would mean it replaced not only the gym, but also a bunch of weights and bands and stuff that are otherwise taking a bunch of space. Only better if the user primarily wants to do resistance stuff, though.
