XTERRAFitness Sport Series Premium Folding Smart Treadmill, Handlebar Speed and Incline Controls, Large XTRASoft Cushioned Running Deck, Built-in FTMS-Enabled Bluetooth with XTERRA+ Fitness App

This treadmill (TRX3500) is better than I expected.Overall, very happy with the purchase so far, especially with how budget friendly it was at $780 at the time we bought it. It was important to me to get a unit with at least 3.0HP since my spouse planned on doing a lot of running with it, and it hasn't disappointed so far. Other treadmills we had looked at were the NordicTrack 6.5S (only 2.6HP), Sole F80, and the Cardio 3G. Since we're first time treadmill owners, we thought we'd take a chance on this one as the specs seemed like it would be good value for the money spent with a decently sized belt (20x60) and a stronger motor. I see that it's dropped $40 since so it's an even better deal now!Assembly was easy between two people. Lubricating the treadmill with the provided lube was annoying because you had to loosen the belt significantly to get under it, and even then, it was not easy to lube, and it was annoying to have to tighten the belt back since it requires quite a bit of time and adjustments. For the first several weeks, I noticed that it was clunking when landing, so I ended up buying a different lube that has a long tube to dispense the lubricant without having to loosen the treadmill belt and it works wonders. Now the unit is a lot quieter and smoother as well. Stability was never an issue for me or my spouse, and we use the tablet holder on the display unit to hold our tablets with no real issues there either.Some stats in 5 weeks of usage:me- 5'2" 128 lbs- 12h of a mix of walking, speed walking, jogging- treadmill speed between 2.5-5 mph used- average of 7 miles/week- incline up to 8 usedmy spouse- 5'10" 155 lbs- 55h of a mix of walking, jogging, running, and speed intervals- treadmill speed between 3-10mph used- average of 55 miles/week- incline up to 8 usedWe live in an area that gets over 80" of snow a year, so the treadmill has definitely gotten plenty of love. The shock absorption is noticeable as running outside on concrete for the first time in weeks made my joints pretty sore.The only negative point I have about the treadmill so far is that sometimes the display screen has gone wonky, with it getting pixelated randomly, or the speed display showing as much higher than the speed it actually is without adjusting it. This did not affect the actual speed of the belt though. There is also a slight incline even at 0 incline which is fine. Currently, we are lubing and vacuuming the motor every 2 weeks for maintenance. I admit, at the price point, I expect that it'll break at some point prematurely, but so far, it's been rock solid.

Excellent treadmill, not quite commercial gym quality but solidly built with sweet blue LCD screen and Bluetooth FTMS that works great with Zwift and Kinomap. I put this together myself but had to lay on my back and hold up the verticals with my feet using my hands to connect the wiring and bolt the verticals to the base, definitely a job meant for two people.The box is huge and heavy, looked okay but my motor cover was cracked. Called Spirit and they registered the treadmill and shipped me the replacement cover. Kudos to Spirit for answering the phone quickly and taking care of the shipping damage without any hassle.I am 6'-0", 235# and jog, run intervals and race pace on this thing no problem. The motor is powerful enough and the frame sturdy. Mainly use the treadmill with Zwift and Kinomap. Zwift works fine but they still won't implement auto incline control so it isn't as seamless as it could be. Kinomap however does control the treadmill's incline and it is really nice, but the video quality is hit or miss. Bluetooth FTMS works great on the TRX4500.Pure manual mode is nice too. The readout shows not only speed in mph but pace which is nice and you get a visual of a track which helps with intervals.When jogging and running, the console does shimmy so trying to watch Netflix on your tablet is going to be frustrating, but you're golden if you are just going to be walking. I'm using a stand mounted TV for the running apps and watching YouTube or Netflix so it's a non-issue. The True and Life Fitness treadmills at the gyms I go to are more solid with just a bit of mild console shimmy when running. The Xterra has about the same I noticed in the Soles, Proforms and NordicTracks I tried out before buying the Xterra.Overall a solid treadmill capable of running and interval training with linebacker sized runners, FTMS Bluetooth for Zwift and Kinomap and a great value.
