At first, I was a bit skeptical about a bandsaw this cheap. It's certainly not ad industrial-grade machine, but it does its job perfectly fine. I could seamlessly cut 20mm mild steel square bars (both hollow and solid), aluminum bars, cast iron (30mm), and more while still using half its maximum power setting.
The tool doesn't come with an automatic lubrication system, however, you can always spray some lubricant manually while the blade is cutting.
During my test cuts (where I manually sprayed lubricant from time to time), the blade always stayed cool to the touch.
Although cheap, the bandsaw didn't have any vibration problems when cutting solid bars, and just some slight vibrations when cutting thin hollow stock, which was predictable.
The only feature it's missing is the ability to set the blade vertically to use it as a table bandsaw like those used in woodworking.
