The running belt construction is very well made. I have used it for about 3 months and experienced no problems. It was also fairly easy to install. Good product and value. Would purchase from this seller again.

I purchased this belt after the one that came with my Horizon Treadmill developed a hole in it. It was easy to replace after viewing a few videos online. The belt feels more substantial compared to the original and seems to be running quite smoothly on the treadmill. This belt is just very slightly (a cm or two) shorter than the original, so you will have to adjust your treadmill tensioning to this difference.

This is a great replacement belt that actually fits my treadmill. I made the mistake of buying a belt that was $30 less from a seller who claims it's for my treadmill model, however, that statement was false and the belt was too small. I returned that one and ordered this one. The belt from Treadmill Doctor fits perfectly, is a smidgen wider than the original belt (which I like) and is much sturdier/better quality than the first belt I received from the other seller. You can't go wrong with this belt or this seller.

I purchased this belt back in 2019 and I can say wholeheartedly that this is one sturdy belt. My neighbor, who got a new treadmill, needed to get rid of their old and I happily took it off their hands. All I had to do was replace the belt and I got a brand new treadmill! My neighbor regrets giving away and purchasing a new. I haven’t had to touch the belt since the day I installed and I will be bringing in the 2024 new year running on this belt. Thank you! !!!!

It seems sturdier than the original belt and fit perfectly. It is a it noisier when walking/running on it, but it's not an issue for me. Ignore the negative reviews as they are reflections of the buyers and not the belt. If it doesn't fit then you send it back. If you are not comfortable working on machines then maybe you should have someone else do the work. Yes the installation required taking much of the machine apart, but it's not too hard if you pay attention to fit and alignment.

After putting around 1000 miles on the original Horizon belt, I almost died on a run one day when the belt folded in on itself. I purchased this belt after reading the good reviews and am very glad I did. It took less than an hour to install and was a perfect fit. The belt feels cushier and sturdier than the original, but it's definitely not quieter. Overall, a great product to keep a good treadmill going.

It is as is stated, it is a one ply not a commercial belt. For my 1mile times 3 a day it will and is working fine. Comes with lube. Just adjust your drag if it slips by 1/4 turns on both ends until it stops slipping. Fast delivery and real reasonable price with free shipping. Can't beat that with a stick! I've had my Horizon T101 for 4 years now, if used right it's one heck of a good machine--just keep your normal maintenance up on it.

Fits okay. Thanks! Now that I've done this I can imagine it would take an hour to do if there is a next time. The belt works just fine. The inner seems to be plastic, too. The original belt had a sort of felt inside which was coming off like fluff, I wondered if the new belt would have to be pulled too tight for traction, but seems to be working fine with appropriate tension on the belt. It had Almost a creasea out of the box, but I spread it out for a few days before replacing and the crease smoothed out.
