This is my first smart trainer, I used to have a Travel Trac Comp Fluid trainer, it's quite nice but when it's not very realistic especially while using with Zwift on hills, with this Tacx Flow Smart Trainer, the ride in Zwift now are so much more fun, the hilly ride is so realistic and more align with my level comparing riding outside. Only flaw is there are a few seconds delay when going uphill, hopefully they can fix in future firmware update..
I use this trainer about 3 days a week to supplement my winter training program. It has a a great real life road feel and connects with ease to Zwift. I highly recommend this product if you're looking for a smart trainer that doesn't brake the bank!
I use this item in my den of pain with Zwift. When I am simply plugged, it pairs with my iPad and Zwift just fine. When I run ANT items like my Garmin alongside the workout then there are weird issues, so I just don't bother tracking with Garmin while I'm on my Tacx. The issue itself is not important enough for me to try to troubleshoot.
