I purchased this Reefmat 500 in September 2023 from BRS and it has jammed 3 times as of today I only had to replace the roll twice. The wheel stopped turning forcing me to go back to socks temporarily (I hope). The gears seem to lock up and stop turning. I reach out to Red Sea for some assistance. They asked me to make a video of the issue. Has anyone else had this experience and what is the warranty replacement like so far? I spoke to one of the local Red Sea dealers here locally and they told me they just replaced their motor last weekend as well because the mat kept jamming.
