This Concept II rowing machine is about 20 years old but rarely used. All mechanical components are in great condition. HOWEVER, the computer works intermittantly. With new batteries, it works fine for about a week. I got tired of installing batteries every week so I used the rower without the computer. The computer simply gives time, speed, distance, and stroke rate. The machine is very smooth and it's a great workout. I don't have room for it anymore. I have pictures if you want to see it.
