I deliberated between different smart trainers for far too long and chose the H3 based on reviews and the fact that it's one of the few Trainer Road recommendations. I couldn't be happier with it. Pairing and updating went smoothly. It works great in both ERG and 'regular trainer' mode. It's an order of magnitude quieter than an old rear-wheel trainer, which I'm coming from. It's not a big deal connecting and removing the bike. Two months in, zero complaints.
I've owned a couple of other trainers in the past and I was a hesitant to spend so much on the H3, but I'm glad I did. This is by far the closest feel to riding on the road. Riding on the H3 is something I actually look forward to, rather than the painful drudgery of my previous trainers. I especially like the ability to realistically coast on the downhills. The massive flywheel is definitely an advantage, plus It's almost completely silent. Paired with Rouvy, I find myself using the H3 even when it's nice outside.
This is my first experience with direct drive trainer and I believe this is the best trainer for the price! I researched DD trainers prior to pulling the trigger on such an expensive item however living in the rocky mountains I spent lots of time riding indoors throughout the year and feel this was a great investment. Super easy set up. Plug in and sync to apps immediately. Smooth transitions between intervals. Quiet..pretty much can only hear my bike's drivetrain. Only complaint (a very minor one) is that when resistance is low it takes a long time to spin down. Very happy with the purchase and highly recommend this trainer!
Got the chance to pick up the Saris H3 to replace my Wahoo Kickr (Gen 3) and I after the first ride I was pleasantly surprised at how different the H3 felt.
Pros: a little quieter, more stable when sprinting, has virtual cadence (no separate cadence sensor necessary), feels smoother, $200 cheaper, includes pop out wheel block, more consistent connection with Apple TV.
Cons: housing design makes it hard to tighten thru axels that have a handle.
Overall I feel that the H3 was a nice upgrade over the Wahoo
Smooth, remarkably quiet and super stable---even when out of the saddle. Simple to calibrate and easy to pair with Zwift. Solid construction and first rate customer service. Great Made in the USA quality.
I already had a first gen Tacx Neo which I generally really like. But long cage mtb derailleurs hit the frame of the Neo (at least my non boost 3T Exploro and Niner Jet 9 do). It's workable but I also don't love the Neo's thru axle adapter approach. So I picked up one of these and like it at least as much as the Neo, maybe more. I will likely pick up a second one for my vacation home to replace the POS Kurt Kinetic Rock n Roll I've been using there for the past few years.
