I had bought the saw in 2010 (when she was still 50, - more expensive) and since then used for numerous boards and small beams. The saw is now the 5th year covered outside and still works. Rust marks can be seen but not a problem. The saw blade was obviously now changed. The extension is rather shaky, but keeps. Otherwise the saw is fixed. For the assembly's needs patience.
I had not expected much but this table saw has proven to be surprisingly useful and robust. Building a house, they should survive.
