Great upgrade from my older Horizon

by John Dean on 04/27/2020

I had an older Horizon T7 treadmill that I had for a few years but hadn't used until recently due to problems with my knees and ankles. But once I did start using it daily, I realized I wanted something a bit more robust. I narrowed down my choices to a few in the $1500 - $2000 range, and the Johnson Fitness just down the road from me had this one, so I went to try it out in person. Night and day difference over the previous one I had although that one cost nearly the same price just three years ago. Technology certainly has improved. This one is far more quiet. It feels solid, very little deck movement when I tested, and far, far more options than my previous treadmill had. The information display makes such a huge difference. And even if I have the main display covered with my iPad, I still get all the important data in a row of numbers below. There is so much more information to get here than my old one offered. I also am a fan of how it automatically uploads details to MyFitnessPal, which lets me track my history without having to fill everything into a text document on my laptop. I wish I had the option to change what it reports activity as (running/walking in place) since I'd rather see "Treadmill" or something as the type of activity. I also wish it recorded distance. All it records is calories burned and time. But still better than the other could do. What sold me on it the instant I tested in store a few months ago though was the roller knobs on top of the hand grips, for instant changes in speed and incline. They work great, and I absolutely love that feature. That was the deciding factor for me in the 7.8 over the 7.4. Motor is strong and silent, and the only real noise I get is an odd echo type of sound of the treadmill being pressed against the board underneath it since it runs a bit above it until you step on it. So it's like a small slightly delayed tap on the board with some footsteps. There is only one complaint I have from it - that fan is just useless. One speed (very low) and it blows at my belly button. What use is that? At least the older Horizon I had blew up at my face, and could be adjusted as well. If this was the best they could do on this machine, it's clear they didn't intend it to be USEFUL - it's just there so they can claim parity with the other manufacturers by saying they have a "fan." But don't expect it to be any use whatsoever. Johnson Fitness delivery and setup was absolutely top notch, gold star service. I had moved the old one out of the space, and since they were taking it, they actually disassembled it and removed it, one less thing for me to deal with, and I received a check then a month or so later and was more than satisfied with the amount since otherwise I would've been stuck with it in the garage waiting for someone who would come and take it away for free. The new unit was assembled on the spot, checked, and even all the cardboard and such hauled away. I had to do nothing other than hold the door open for them to bring parts in to make it easier for them. Both of the guys were friendly and professional. I use this every day, without fail. And I've had it now for 6 weeks, and it has been outstanding. Definitely the best money I've spent on my health.

This is better than the Peloton Tread

by chad davis on 01/09/2021

I bought my Horizon 7.8 AT from Maddie at the Rockville Store. She was extremely nice and knowledgeable. As for the 7.8 AT, it simply is the best home treadmill on the market. Before I made my purchase, I tried out every competing brand (Sole, Nordictrack, Peloton, Pro Form, and Spirit). The Horizon 7.8 AT beat them all. The Peloton and Sole were its closest competitors, but comparing Peloton, the Horizon had a faster motor and changed speeds and inclines faster. Plus, its Blue tooth system allows you to sync with Peloton, iFit, and zwift apps. I mounted a 45 inch Samsung on the wall near the treadmill with Apple Play so thats my monitor instead of paying the extra $2700 for a weaker Peloton monitor. I did like the Sole F 85, but the Horizon 7.8 AT still felt better to run on and had more amenities for a cheaper price. The quality of the 7.8 AT feels like a gym quality treadmill. I love the Sprint 8! It is so smooth between speeds and inclines. It also comes with a Heart Monitor thats pretty good, and I can run the heart monitor, as well as pandora, Peloton app, etc. at the same time through its blue tooth system. The sound system on the Horizon 7.8AT is also very good (easily better than the others). The only negative on the 7.8 AT is the fan. It is in a location that really does not do anything. However, the other positives about the 7.8 AT greatly overweighs this negative. I am 6 ft, 210 lbs and running on the machine is quiet- even when I do the HIIT training. It really is built well. I am obsessed with this machine and have used it everyday since it was delivered. (Do yourself a favor and pay the extra money to have them assemble it. It was worth making sure that it was assembled right).

Treadmill good. Customer service sucks.

by Chip Bendle on 02/22/2021

Please with the treadmill. You can read the details on other reviews but overall I am pleased. The bummer is the heartrate monitor I got with it was defective out of the box. Johnson fit customer service is non-existent. Their support queue tells you to hold on for 20 minutes and stand by while it then disconnects. You email their support through the form, and it tells you they dont do phone support and due to high call volume it may take 10-14 days for a response. Seriously? I bet I could respond to their ENTIRE support queue within 1 day. Pathetic. Even more Pathetic is that I am now at day 12 and not a phone call, or email from them. Basically there is ZERO customer suppport. I have proven that. Good luck.
