Home Bicycle Folding Rollers, Professional Indoor Bike Parabolic Roller, Adjustble Bike Trainers for 24""-29"" Mountain Bike and 700C Road Bike

I bought these rollers from another seller and, I have to say, they're not good. At first they were fantastic but it all went downhill pretty quickly. They last about a month before they crapped out. Below is my original and the updated reviews on the other seller's page. If you still want to get it, the other seller has them for less.UPDATE:I had the back roll break after a month of riding 25kms every day, which started causing a very loud clacking sound. I am about 190lbs and my bike weighs around 18lbs, so, I'm well withing the 150kgs max weight that's indicated. I contacted the seller and he sent me a replacement roll. I got the roll, installed it and everything was working perfectly again. The day after installing the new roll, the other two got cracks too. The noise came back, now coming from the other rolls. This time it was louder because two rolls were cracked. As much as I loved them when I first got them, I'd say, it's not a good product. In the pictures you can see all three cracked rolls.ORIGINAL:This is my second set of rollers. The first one lasted me a little over three years. I was very happy with it until it died about a week ago. Somehow, the back roller got off axis and the whole thing started making loud noises and vibrated like it was going to come apart at any moment. So, I got this one.I have to say, after using it today to ride about 30 miles, it's pretty solid. The noise level is very low. I use it on foam pads and with them, the vibration goes down to almost zero. I live in a 3rd floor apartment and my downstairs neighbors say that this one is less noisy than my previous one. Not that the first one was noisy, it's just that this one is even quieter. Of course, that's going to depend on your tires' tread also.My only complaint about this is, it seems that, with time, the belt is going to snap. With all that vibration, the belt rubs against the frame. My old set didn't have that problem because it was just the bars, so, it had about an inch an a half of clearance. This one has some handles/fasteners to secure the front part of the frame to prevent it from sliding, so, the clearance is about half an inch. The little foot rest's clearance is even smaller. This wouldn't be as big of an issue if, like my old set, it came with a spare belt. I just hope it lasts longer than 3 years.Other than the issue mentioned above, I'm extremely happy with them. I would definitely get another set if this one ends up crapping out or, if the belt snaps, buy just the belt. If they wanted to do right by the customer, they would simply add the extra belt... it can't be more than a few extra cents to them.
