I love this thing. I use it several times per week to get my cardio minutes in. You can cruise leisurely in zone 2 or you can HIIT hard to get into Zone 4 or 5 pretty quickly (well, my fat ass gets there quickly, anyway). The LCD screen is simple and clear, powered by double A batteries that usually last a couple months even with frequent use (I've switched to using rechargeables so the consumable cost is minimal after the initial battery purchase). I don't know how accurate the mileage or calorie counts truly are, but it does provide them. My only construction complaints with this air bike are 1) the sliding phone tray is flimsy and when riding hard the phone always seems to vibrate out of it eventually 2) the water bottle is mounted so high on the LCD screen stem that it becomes a real PITA to pull it and replace it while actively peddling. A couple things to bear in mind: it gets pretty noisy when riding hard (not relevant if you're wearing earpods but it's hard to hear music on your phone or a smaller bluetooth speaker) and it also produces quite a good air blast, so depending on where that jet stream is pointed it might make an impact if you're setting it up in your house. One aspect that is really nice, is that even though the bike is quite stable, this is light enough to readily roll it away or even pick it up and reposition it when not in use. I set mine on our treadmill when not using either to get it out of the middle of the floor in the basement.
