I have a life fitness T7 treadmill that I bought brand new and used for a year at home when I was training for a marathon and I only used it when it was poring with rain outside so it's had very light usage. I then put it into storage whilst I travelled the world. I'm now going to live aboard permanently so it has to go. it's currently in a container in sidmouth so you will need to collect in a van. it hasn't been used for about 5 years so I think you will need to do a bit of a service to check all is good which was my intention if I started to use it again. I will get some better photos and I'll take down a mains power pack to show it working.
