My MX8 Elite is great other than the track issue. It goes through a set of tracks like every 3-6 months, which is insane. In fact it got so bad I purchased the Polaris Atlas XT, but I keep the MX8 for backup. If I knew I could get tracks this cheap I probably wouldn't have purchased a new pool cleaner. At the local pool store the prices were expensive when I purchased the MX8 years ago, but now they have doubled (if not more) in price. I think just one track is $30 - $50 bucks, not a set, just one. That should be illegal. Anyways these tracks fit on to my MX8 without much issue, standard procedure. The build quality at least seems similar to OEM, hard to tell whats best until after a while of use. If I remember correctly, I want to say they are a bit looser than the OEM ones which to be honest is not a good thing, you want those tracks on tight. It's tight enough to work, so it's not a deal breaker. If these last even a fraction of the OEM ones, these are still the way to go, plus you aren't supporting the company charging astronomical prices for tracks. One other small complaint is the packaging; they really just had mine wrapped in tape (inside a standard Amazon envelope). They also taped it in a way where it might be stretching the tracks, but the biggest problem was getting them out without cutting the tracks. Again, small issue and an easy fix, just put them in a plastic bag; it might have even been a 1 off thing that happened to me. Anyways the bottom line is the price on these is amazing and if they work even just a month, it will make it worth it for me. Time will truly tell how well these turn out so I will have to make an update. Are they as good as OEM? Probably not. Are they best way to buy tracks for your MX pool cleaner? Most likely. Would definitely suggest this to anyone who has an MX pool cleaner. Read more

It's hard to tell exactly when to change the tracks on your automatic pool cleaner, but sooner or later, the pool just isn't getting cleaned as well or as fast. The first step is to obviously check and clean the filters, but soon after that, you should take a look at your robot to make sure it's actually moving. If the cog wheel spins but the tracks do not, changes are your teeth are worn down. The bad thing is that you usually can't just look at it because you have nothing to compare to. Get yourself a set of these and keep them with your pool stuff for when you eventually need them. For us, it seems to be a yearly occurrence, but if you have a long pool swimming season, it could be less. These are a great value and appear to be well made. Read more
