So like a lot of us, I have been running EcoTech products for years. A few times back in the twenty teens I had some issues and they were resolved immediately as you would expect when paying a premium price. Now here we are after a few buyouts and mergers and I have been fighting for a simple defective part replacement on a brand new product purchased at retail from an authorized brick and mortar seller. A new MP-10 has a simple issue, the impeller is too tight so it seizes and falls off. I am an experienced reefer so I keep a spare wet side on hand for cycling through cleanings with no downtime so I was able to use that one and figured no big deal, Ecotech will take care of it. Here we are 2 months later (partially my fault for not having time to jump through their hoops right away. Pics, videos, serial numbers etc.) and countless emails and I still have not received a part. Absolutely unacceptable! Really doubtful that I will ever consider another Eco Tech product again.
