Sunny Health & Fitness Cardio Climber is an Elliptical exercise machine that uses some sort of magnetic system instead of the old pulley system. It's a very nicely engineered device that is well made with solid metal parts. The hardware is not cheesy at all. The device itself is very smooth to use so the magnetic system is a super upgrade over previous types of ellipticals. In this video I went through the step by step instructions on how to assemble this unit. Hopefully it will help if the instructions are missing or you just prefer a video guide instead! DIY Do it yourself fun!
