Summary: A great local company with high quality products and service!Long Version: I am a machinist at a local machine shop and have been using one of Armstrong Magnetics LiftMag NL-330B lifting magnets for over two years now. We do a lot of steel components to support welding fabrication, as well as various street jobs. This magnet has moved literally tons of steel and has done an excellent job.There are generic magnets that get you by, and high quality magnets that are a joy to use, and the LiftMag series of magnets falls into the latter category. The compact size fits onto smaller blocks & helps when loading parts into tight machine fixturing, And the safety-checking position & information pamphlet let you test your load & lift with confidence.But the best part of the LiftMag series is that when the magnet is off, there is absolutely no residual magnetic field; you simply move the magnet exactly where you want it, then flip the lever to ON. Additionally, the Armstrong LiftMag series can be safely wiped down without the danger of cutting yourself on metal shaving, and it always gives you consistent lifting performance without damaging a newly machined surface (unlike the get you buy magnets that you have to pry off of the work piece).Armstrong Magnetics, Inc. also sells a variety of other great magnets. So go support a great local company & buy some magnets!
